H-1B Transfer Guide 2026
Changing H-1B employers? This free tool covers the four questions everyone asks: what it costs (fee calculator), how long it takes (timeline estimator), whether you qualify (eligibility checker), and what to prepare (document checklist).
No new lottery is needed if you were already counted against the cap — and under AC21 portability you can start the new job once the petition is filed. Work through the tabs below.

How to Use the H-1B Transfer Tool
1Calculate the fees
Open the Fee Calculator tab and select the new employer's size — that sets the ACWIA training fee ($750 vs $1,500). Toggle premium processing to see the 15-day option. The breakdown shows every USCIS fee line by line.
2Estimate your timeline
Switch to the Timeline Estimator and compare regular (2–4 months) vs premium (15 business days) processing. The visual timeline shows each stage — and the AC21 note explains when you can legally start work.
3Check your eligibility
Answer the five yes/no questions honestly — status, cap count, 6-year clock, job offer, and recent pay stubs. You'll get an instant read: likely eligible, needs review, or see an attorney first.
4Track your documents
Use the Document Checklist tab as your packing list. Check items off as you collect them — the progress bar shows how close your petition package is to complete.

How H-1B Transfers Work
Despite the name, nothing is "transferred." Your new employer files a new Form I-129 petition with USCIS, requesting H-1B classification for you. Because you were already counted against the annual cap, no new lottery registration is needed — the petition reuses your existing cap number. The petition must include a certified Labor Condition Application (LCA) for the new role and evidence that the job qualifies as a specialty occupation.
AC21 Portability: Start Work Before Approval
The single most useful rule in H-1B transfers: under AC21 §105 portability, once the new employer's petition is timely filed and USCIS issues the receipt notice, you may begin working for the new employer immediately — approval can come months later. The risk: if the petition is ultimately denied after you've started, you fall out of status. Many workers mitigate this by waiting for the receipt (not the approval) before resigning, or by paying for premium processing to collapse the uncertainty window to 15 business days.

Common H-1B Transfer Mistakes
- Resigning before the receipt arrives. AC21 portability requires a filed petition with receipt — quitting on the promise of a filing leaves you unprotected.
- Letting status lapse. A gap between jobs beyond the 60-day grace period (or without valid status) can doom the transfer.
- Assuming the lottery is needed again. Cap-counted workers don't re-enter the lottery — but cap-exempt-to-cap moves are the tricky exception.
- Ignoring the 6-year clock. Time recapture and AC21 extensions (pending PERM/I-140) change the math — confirm remaining H-1B time before switching.
H-1B Transfer FAQs
What is an H-1B transfer?
An H-1B "transfer" is technically a change-of-employer petition: your new employer files a new Form I-129 petition with USCIS asking to employ you in H-1B status. Nothing is literally transferred — it is a brand-new petition that reuses your existing cap count, so no new lottery registration is needed if you were already counted against the cap.
How much does an H-1B transfer cost?
For the employer, typical government fees are the $460 I-129 filing fee, a $750 or $1,500 ACWIA training fee (depending on employer size), and a $500 fraud prevention fee — roughly $1,710 to $2,460 before optional premium processing ($2,805). By law the employer must pay the ACWIA and fraud fees; the worker cannot be asked to cover them. Use the fee calculator above for an exact breakdown.
How long does an H-1B transfer take?
With regular processing, expect roughly 2–4 months from filing to approval, varying by service center. With premium processing ($2,805), USCIS guarantees a decision — approval, denial, or RFE — within 15 business days. Importantly, under AC21 portability you may begin working for the new employer as soon as the petition is filed (receipt issued), without waiting for approval.
Can I start working for the new employer before approval?
Yes — this is AC21 portability. Once USCIS issues the receipt notice for the new employer's timely-filed, non-frivolous H-1B petition, you are authorized to begin employment with the new employer while the petition is pending. You do not need to wait for the approval notice.
Do I need to go through the H-1B lottery again to transfer?
No, if you have already been counted against the cap. A change-of-employer petition reuses your existing cap number — no new registration or lottery selection is required. The main exception is if you are moving from a cap-exempt employer to a cap-subject employer without ever having been counted; that generally requires going through the cap.
What happens if my H-1B transfer is denied?
If the transfer petition is denied while your underlying H-1B status with the prior employer is still valid and you have not yet left that job, you generally remain in status with the original employer. If you already started working for the new employer under AC21 portability and the petition is denied, you fall out of status unless you have another valid status — which is why many workers wait for approval or keep the old job until the receipt arrives. Discuss timing strategy with your attorney.
Does the $100,000 H-1B fee apply to transfers?
The September 2025 proclamation announced a $100,000 fee on certain new H-1B petitions, and its scope and legal status have been contested since. Whether it applies to change-of-employer petitions in your case is a question for your immigration attorney — toggle it in the fee calculator above to see the arithmetic, but do not rely on it without legal confirmation.
What documents do I need for an H-1B transfer?
The standard package includes your passport, I-94 record, recent pay stubs (last 2–3 months), current I-797 approval notice, the new job offer letter, a certified LCA for the new role, degree certificates and transcripts (plus a credential evaluation for foreign degrees), and your resume. Use the interactive document checklist above to track your progress.
