H-4 Visa Guide 2026: Stamping, Status, Work Rules, and the Age-21 Playbook

The H-4 visa is the visa for the family of an H-1B worker — the spouse and the unmarried children under 21. It lets them live in the United States for as long as the H-1B worker keeps valid status, but it is not a work visa, it is not independent, and it ends the day a child turns 21. This guide covers the whole H-4 journey in one place: who qualifies, how stamping abroad works step by step, how to extend or change to H-4 inside the US, what H-4 lets you do and what it does not, and the age-21 playbook every family should start early — with every rule tied to its official source.

What is the H-4 visa? Stamp vs status vs I-94, explained

Three words get mixed up constantly, and the confusion causes real mistakes. Keep them separate and most of H-4 becomes clear.

The visa stamp is the foil placed in your passport at a US consulate abroad. It only lets you travel to a US port of entry and ask for admission. It is not permission to stay, and it is not permission to work.

Your status is what you hold once you are inside the US — H-4 status, granted when you enter or when USCIS approves a change or extension of status. Status is what lets you live in the US, and it is what ends when the principal's status ends.

The I-94 record is the official record of your admission, held by Customs and Border Protection. It states how long you are actually allowed to stay. When people say “my visa is valid for three years, so I can stay three years,” they are usually wrong — the I-94 date governs, not the stamp's expiry date. Check your I-94 at i94.cbp.dhs.gov after every entry and keep a copy with your immigration papers.

H-4 exists only as a dependent category. There is no standalone H-4: no principal in valid H status, no H-4. That single fact explains the extension rule, the grace-period rule, and the age-out rule below.

The two routes at a glance — abroad you get a stamp, inside the US you get a new I-94. Both end at the same H-4 status.

Figure: the two routes to H-4 — a consular stamp abroad, or a Form I-539 change or extension inside the US.

Who qualifies — and who does not

Federal regulations limit H-4 to two groups: the lawful spouse and the unmarried children under 21 of an H-category worker. That is the whole list.

A spouse qualifies on the basis of a legally recognized marriage to the principal. The marriage certificate is the single most scrutinized H-4 document — carry the original, not just a copy. If the marriage is under two years old, carry supplementary proof as well: wedding photos, a joint bank account, a joint lease. Officers check newer marriages more closely.

A child qualifies if unmarried and under 21. Both conditions must hold. A child who marries before 21 loses eligibility, and a child who turns 21 loses it on their birthday — there is no grace period built into the age rule itself. The age-out playbook later in this guide covers what to do before that day arrives.

Who does not qualify, no matter how close the relationship: a parent, a sibling, an unmarried partner, a fiancé, or a child who has already turned 21. None of them can get an H-4 stamp or H-4 status through the principal. They need their own visa category.

H-4 is not limited to dependents of H-1B workers specifically. The regulation covers spouses and children of any H-category nonimmigrant, including H-1B, H-1B1, H-2A, H-2B, and H-3 workers. In practice, the overwhelming majority of H-4 holders are H-1B families.

H-4 in numbers

The American Immigration Council's H-4 fact sheet, published October 2026, gives the clearest public picture of the category. These are official-adjacent counts worth knowing before you read the process sections — they show how big, and how India-centered, this audience is.

The India number matters for this guide's audience: most H-4 families reading it are Indian families, and most of the consular practicalities below — appointment backlogs, document scrutiny, marriage proof — bite hardest at Indian consulates.

What changed for H-4 in 2025 — read this first

Three policy shifts in 2025 changed H-4 practicalities more than anything in the previous five years. Older guides — and older advice from friends — still describe a world that no longer exists. Here is the current picture.

Third-country stamping largely closed (September 6, 2025). The State Department directed most nonimmigrant visa applicants to apply at a post in their country of nationality or legal residence. The old workaround — an Indian H-1B family flying to Toronto or Mexico for a faster appointment — is generally no longer available. One nuance survives: people legally resident in the US may still be accepted at some Canada/Mexico posts if they can prove US residence (for example with an I-797 and an employer letter). Do not book travel on that nuance without confirming with the specific consulate first.

In-person interviews are now generally required (October 1, 2025). The interview-waiver (“dropbox”) path that many H-1B and H-4 renewals relied on has been narrowed sharply, and for H-1B holders it is effectively gone. Some H-4 renewal guides still describe dropbox under the old 12-month rule. Treat those passages as outdated until your consulate confirms otherwise: plan for an in-person interview, and treat any waiver as a bonus, not a plan.

Domestic renewal is not available. The 2024 pilot that briefly let some H-1B holders renew their visa stamp inside the US has been suspended, with no confirmed restart date. All H-4 stamping still happens at a consulate abroad. The in-US route is a change or extension of status (Form I-539), which is not the same thing as a stamp — see the stamp-vs-status explainer above.

A fourth change belongs to the work-permit track, not the visa track, but families confuse the two constantly: automatic EAD extensions ended for renewals filed on or after October 30, 2025. That is covered in the EAD section below and in full in our H-4 EAD guide.

Getting the H-4 stamp abroad, step by step

This is the route for dependents outside the US, or inside the US who travel abroad and need a new stamp to return. The sequence is the same at every consulate; only wait times and local instructions differ.

Step 1 — Complete Form DS-160. Every applicant needs their own DS-160, including children — even infants. Fill it online at the State Department's Consular Electronic Application Center, and print the confirmation page. Check every answer against the principal's petition: DS-160 inconsistencies are one of the most common triggers for extra scrutiny and administrative processing later.

Step 2 — Pay the visa fee. The H-category Machine Readable Visa (MRV) fee is $205. It is non-refundable, even if the visa is refused. Confirm the current fee on the State Department's fee page before paying — fees change, and a wrong payment can cost you your appointment slot.

Step 3 — Book the appointment. Create a profile on your consulate's scheduling system and book the interview (and biometrics, where the post requires it separately). Book in your country of nationality or legal residence — see the 2025 changes above. Appointment backlogs vary wildly by post; Indian consulates have been among the most backlogged, so book as early as your travel allows.

Step 4 — Attend the interview. Bring every document in the checklist below, in original plus one copy where noted. Interviews for H-4 are usually short and focused on two things: the relationship to the principal, and the principal's current employment. The question bank below lists what to expect.

Step 5 — Receive the stamp and check your I-94 on entry. If approved, the passport is returned with the visa foil, usually within a few business days. On entry to the US, check the I-94 record immediately — the I-94 date, not the stamp's expiry, is how long you may stay. If the I-94 date is shorter than expected, raise it with CBP at the airport before leaving, not weeks later.

Documents checklist — what to carry to the consulate

Officers check different documents for H-4 than for H-1B. The relationship proof and the principal's employment evidence matter more than anything else. Use this as a packing list.

Bringing too much documentation is rarely a problem. Bringing too little — especially a missing marriage certificate or a missing I-797 copy — is one of the fastest routes to a 221(g) document request and a delayed stamp.

Stamping together, separately, or by dropbox

Families usually stamp in one of three patterns. Each has its own practicalities.

Together with the principal. The simplest pattern: the whole family attends together, and the principal's documents are right there. Officers can verify the relationship and the employment in one conversation.

Separately, principal already in the US. The dependent attends alone and carries copies of everything the principal would have shown: I-797, pay stubs, employment letter, visa stamp. This is the pattern where missing paperwork hurts most, because there is no principal in the room to fill the gap.

Renewal by interview waiver (“dropbox”).Under the old rules, H-4 renewals in the same classification, with a prior visa expired within 12 months and no prior unresolved refusals, could often renew without an interview. Since the 2025 narrowing, do not assume this is available for your case: many posts now call H-4 renewals for in-person interviews too. Check your consulate's current interview-waiver instructions before choosing this route, and have an interview plan ready as the fallback.

The interview — questions to expect

H-4 interviews are usually shorter than H-1B interviews, and the questions cluster around the relationship and the principal — not around the dependent's own qualifications. Prepare short, consistent answers to these:

• How are you related to the principal, and when did you marry?
• Where does your spouse work, and what do they do?
• What is your spouse's salary?
• Where will you live in the US?
• Are you traveling together or joining later?
• Have you been to the US before, and on which visa?
• Do you plan to work or study in the US?
• For children: who are your parents, and where do they work?

Two honesty notes. First, “do you plan to work” is not a trick question — the correct answer for an H-4 holder without an EAD is no, and claiming otherwise can create a record that hurts a later EAD application. Second, your answers must match the petition and the DS-160 exactly. A salary figure that differs from the LCA, or a work location that differs from the petition, is how a routine interview turns into administrative processing.

Changing to or extending H-4 inside the US (Form I-539)

Dependents already in the US do not need a consulate to get or keep H-4 status. They file Form I-539 with USCIS — to change from another status to H-4, or to extend H-4 when the principal's H-1B is extended. Each dependent needs their own I-539A supplement where applicable, and the filing should include proof of the relationship and of the principal's current status.

File before the current status expires. A timely filed I-539 extension lets you remain in an authorized period of stay while USCIS decides, even if the old I-94 date passes. It does not grant work authorization — that needs a separate EAD application, covered below.

Bundling: when the principal files an H-1B extension, the family's I-539 applications are often filed together with it. Bundling keeps the cases aligned, but it does not guarantee aligned decisions — the H-4 cases can lag behind the principal's approval. Premium processing on the principal's H-1B petition does not automatically speed up the H-4 I-539, so check current USCIS premium-processing eligibility for I-539 before assuming anything about timing.

Travel while an application is pending: this is where families get hurt. Leaving the US while a change of status application is pending generally abandons it. Leaving while an extension is pending is less absolute, but returning requires a valid H-4 visa stamp — which means a consulate trip and a new interview. Do not book international travel while an I-539 is pending without checking the consequences for that specific filing first.

Staying in status — and the 60-day grace period

H-4 status follows the principal. If the principal's employment ends, the principal gets a discretionary grace period of up to 60 days (or until the I-94 expires, whichever is sooner) to find a new sponsor, change status, or depart — and the dependents' clock runs with the principal's. The grace period is not work authorization for anyone in the family, and it is not an extension of status. It is time to act, nothing more. Our H-1B grace-period guide covers the principal's side in full; the family side follows the same dates.

If the principal changes employers (an H-1B transfer), the dependents do not automatically move with them. The H-4 extension should be filed alongside the transfer, or the family can fall out of status while the principal's case is approved. If the principal changes to a different visa category altogether, the dependents need a matching change — H-4 only attaches to H status.

Keep a status calendar for the whole family: every I-94 expiry date, every petition validity date, and every pending filing's receipt date. Most H-4 status problems are not legal puzzles — they are missed dates.

Work, study, and daily life on H-4

H-4 is a residence status, not a work status. Within that frame, daily life is fairly broad — but the boundaries are strict, and crossing them has consequences.

In-state tuition is the one item that varies enough to deserve its own check: some states grant it to H-4 dependents, others do not, and the rules change. Confirm with the specific university before budgeting around it.

Work authorization — the short version

This section is deliberately short, because the full subject already has its own guide. If you need the work-permit process, read our H-4 EAD guide. The summary is:

• H-4 status alone never authorizes work — not for spouses, not for children, not for remote work, not for self-employment.
• Only certain spouses can apply for an EAD: those whose principal has an approved I-140, or whose principal holds H-1B status extended beyond six years under AC21.
• H-4 children cannot get work authorization through this rule at any age.
• Renewals filed on or after October 30, 2025 no longer carry an automatic extension: if the card expires before USCIS approves the renewal, work must stop until the new card arrives.

Everything else — the two qualifying paths in detail, the I-765 filing steps, the fee, and honest processing times — lives in the EAD guide, and this guide links there rather than repeating it.

When a child turns 21 — the age-out playbook

This is the section families find too late, so read it first if you have a teenage child on H-4. The rule is simple and unforgiving: H-4 eligibility ends on the 21st birthday. There is no extra grace period in the age rule, and the Child Status Protection Act (CSPA) — often mentioned in this context — helps green-card cases, not H-4 status itself. Do not let anyone tell you CSPA “freezes” H-4 age. It does not.

Work backwards from the 21st birthday, not forwards from today:

Figure: the age-out timeline — plan backwards from the 21st birthday, and file the change of status before it.

• 12+ months before 21: choose the next status. For most children in school, that is F-1 student status: get the I-20 from the school, understand the F-1 work limits (on-campus work, and CPT/OPT only under F-1 rules), and confirm the school's timeline.
• 6–12 months before 21: file the change of status (Form I-539, from H-4 to F-1) with enough lead time for USCIS processing. A change filed too late, or denied after 21, leaves no H-4 to fall back on.
• Before 21, always: keep the child's status unbroken. Any gap — an expired I-94, a denied filing with no backup — can complicate every later application, including the green-card case the family may be pursuing.

The human scale of this problem is large: the American Immigration Council estimated about 224,000 “Documented Dreamers” — children of legal temporary workers, many of them H-1B families — facing the prospect of having to leave the US if they cannot secure another status by 21. If your family is also in a green-card process, coordinate the age-out plan with that case's priority date and attorney — the two timelines interact, and the right move depends on both.

Refusal, 221(g), and delays

A refused H-4 stamp is not always a denied case, and the most common confusion in this whole area has a name: 221(g).

Section 221(g) of the Immigration and Nationality Act lets a consular officer pause a visa case when more evidence is needed — missing documents, or additional administrative processing such as background checks. The passport is usually returned, and the case stays open. That is a hold, not a final denial, and most 221(g) cases resolve once the documents arrive or the checks finish — commonly within two to six months, though some take longer.

The confusion comes from the status screen: since March 2020, the State Department's CEAC tracker shows cases under administrative processing as “Refused.” That label alarms families, but in a 221(g) case it usually means the review is still open, not that the visa is finally denied. The letter handed over at the interview — not the CEAC label — tells you which situation applies and what, if anything, you must submit.

If the letter requests documents, you have one year from the refusal date to submit them; within that year the case reopens without a new DS-160 or a second fee. After it, both are required. Do not book a new interview unless the consulate tells you to — it can complicate the record. And keep the principal's petition valid through the delay: a long 221(g) wait can outlast a petition validity period, in which case the petitioner may need to extend or refile.

A true refusal is different: a 214(b) refusal (failure to show nonimmigrant intent) or a 212(a) ineligibility generally requires a new application to overcome. If you receive either, get the refusal grounds in writing and take advice before reapplying — reapplying unchanged after a 214(b) refusal usually produces the same result.

Fees and forms at a glance

Fees and filing addresses change. Confirm every figure on the linked official pages in the Sources section before filing — a fee paid at the wrong amount is one of the most avoidable causes of a rejected filing.

Mistakes that cause delays or refusals

• Missing marriage or birth proof. The original marriage certificate (spouse) or birth certificate (child) is the foundation of the case. Copies alone, or a missing certificate, invite a 221(g) document request.
• Answers that do not match the petition. A salary, job title, or work location in the interview or DS-160 that differs from the principal's LCA and petition turns a routine case into administrative processing.
• Planning around dropbox or third-country stamping. Both shortcuts narrowed sharply in 2025. Plan for an in-person interview in your home country, and treat anything else as unconfirmed until your consulate says otherwise.
• Traveling while an I-539 is pending. A change-of-status application is generally abandoned by departure. Check before booking, every time.
• Starting the age-out plan too late. A change to F-1 needs months of lead time. The 21st birthday is a deadline, not a reminder.
• Working without an EAD. H-4 status alone authorizes no employment — including remote work and self-employment. Unauthorized work can damage later immigration benefits for the whole family.
• Ignoring the I-94. The stamp gets you in; the I-94 decides how long you may stay. Check it after every entry.

Frequently Asked Questions

What is an H-4 visa?

The H-4 is the dependent visa for the spouse and unmarried children under 21 of an H-category worker, most commonly an H-1B worker. It lets them live in the US for as long as the principal keeps valid status. It is not a work visa and it is not independent of the principal's status.

Who can apply for an H-4 visa?

A lawful spouse and unmarried children under 21 of an H-1B, H-1B1, H-2A, H-2B, or H-3 worker. Parents, siblings, unmarried partners, and children who have turned 21 or married cannot qualify, regardless of the relationship.

Can H-4 visa holders work in the US?

Not on H-4 status alone. Only certain spouses — those whose principal has an approved I-140, or holds H-1B status extended beyond six years under AC21 — can apply for an Employment Authorization Document (EAD). H-4 children cannot work under this rule at any age. See our H-4 EAD guide for the full process.

How do I apply for an H-4 visa stamp?

Complete Form DS-160 (one per applicant, including children), pay the $205 H-category visa fee, book an interview at a consulate in your country of nationality or legal residence, attend with the documents in the checklist above, and check your I-94 record after entry.

What documents do I need for H-4 stamping?

Passport valid 6+ months, DS-160 confirmation, appointment letter, the marriage certificate (original + copy) for a spouse or birth certificates for children, and the principal's I-797 approval notice, recent pay stubs, employment verification letter, and visa stamp copy. Extra marriage proof helps if the marriage is under two years old. The full checklist is in the documents section above.

Can I get my H-4 stamp in Canada or Mexico?

Generally no longer. Since September 6, 2025, the State Department directs most nonimmigrant applicants to their country of nationality or legal residence. People legally resident in the US may still be accepted at some Canada/Mexico posts with proof of US residence, but confirm with the specific consulate before booking travel.

Is dropbox available for H-4 renewals?

Do not count on it. Interview-waiver (“dropbox”) eligibility narrowed sharply through 2025, and most H-1B/H-4 applicants are now called for in-person interviews. Some consulates may still offer it in narrow cases — check your consulate's current instructions and keep an interview plan ready.

How do I extend H-4 status inside the US?

File Form I-539 with USCIS before the current status expires, with proof of the relationship and of the principal's current status. A timely filing lets you remain in an authorized period of stay while USCIS decides. It does not grant work authorization.

How long does H-4 processing take?

Consular stamping usually takes days to a few weeks after the interview, but appointment backlogs vary widely by post and can add months. In-US I-539 processing is measured in months and varies by service center. A 221(g) administrative-processing hold commonly resolves within two to six months but has no fixed deadline.

What happens if the H-1B worker loses their job?

The dependents' clock follows the principal's. The principal gets a discretionary grace period of up to 60 days (or until the I-94 expires, whichever is sooner) to find a new sponsor, change status, or depart — and the family must act within the same window. The grace period is not work authorization for anyone.

What happens when my child turns 21 on H-4?

H-4 eligibility ends on the 21st birthday. Plan 12+ months ahead: for most children in school, the next status is F-1, which needs an I-20 and a change-of-status filing with enough lead time. The Child Status Protection Act helps green-card cases — it does not freeze H-4 age. See the age-out playbook above.

What does 221(g) mean for my H-4 case?

It means the consular officer paused the case for more evidence or additional checks. It is a hold, not a final denial. The CEAC tracker showing “Refused” during administrative processing is normal since March 2020 and does not mean the case is finally denied. If documents were requested, you have one year to submit them.

Can H-4 dependents study in the US?

Yes — full-time or part-time, without a student visa. But there is no CPT or OPT on H-4: practical training requires F-1 status. In-state tuition rules vary by state and university, so confirm with the specific school.

Do H-4 holders get a Social Security Number?

Only with work authorization — that is, only a spouse holding a valid H-4 EAD. Without an EAD, apply for an Individual Taxpayer Identification Number (ITIN) instead for tax filing.
