By Muhammad TalhaBefore any H-1B petition reaches USCIS, the employer must first get a Labor Condition Application (LCA) certified by the U.S. Department of Labor. The LCA is not the visa, and it is not the petition — it is the employer's sworn filing that the job pays the required wage, that working conditions will not be undercut, that no strike or lockout is underway, and that the existing workforce has been told about the filing. This guide is the employer playbook for that filing, end to end: choosing the occupation and wage, completing ETA Form 9035/9035E in the DOL FLAG system, handling every worksite case, running the posting notice correctly, surviving a denial, and keeping the file the law requires afterward. For what the wage levels mean and how to read LCA salary data, see the H-1B Salary Database Guide — this guide covers the filing itself, not the salary tables.
Key facts — the H-1B LCA at a glance
- Form: ETA Form 9035/9035E, filed electronically through the DOL Foreign Labor Application Gateway (FLAG) system.
- Review: DOL reviews within seven working days — for completeness and obvious errors only, not for the merits of the job or the worker.
- Timing: an LCA must not be submitted more than six months before the employment start date.
- Validity: a certified H-1B LCA is valid for up to three years — the end date on the LCA controls.
- Notice: workers must be told on or within 30 days before the LCA is filed, and the notice stays up for 10 days.
- Certified does not mean approved: a certified LCA only lets the employer file the petition with USCIS. USCIS decides the petition separately.
What an LCA is, and why it comes first
A Labor Condition Application is the employer's application to the Department of Labor's Office of Foreign Labor Certification, filed before any H-1B petition. It covers specialty-occupation workers and fashion models of distinguished merit and ability, and the same form serves the H-1B, H-1B1, and E-3 programs. The H-1B process has two doors, in order: first DOL certifies the LCA, then USCIS adjudicates Form I-129, the petition. USCIS requires evidence of a certified LCA with the petition — a petition filed without one cannot proceed.
The LCA is an attestation-based filing. That is the single most important thing to understand about it. DOL does not approve the job, the worker, or the company's hiring decision. It checks that the form is complete and that nothing on it is obviously inaccurate, and the employer attests that everything on it is true. The burden of proving the truth of the filing sits with the employer — which is exactly why a sloppy LCA comes back later as a petition problem or a DOL investigation, even though DOL certified it in a week.
The four attestations
Every LCA carries four sworn promises. They are not boilerplate; each one creates a continuing obligation that outlasts the filing itself.
| Attestation | What the employer promises | Where it bites later |
|---|---|---|
| Wages | Pay at least the required wage: the higher of the actual wage paid to similarly employed workers, or the prevailing wage for the occupation in the area of employment. | Payroll must match the LCA wage from day one; underpayment is a wage violation, not a paperwork slip. |
| Working conditions | Employing the H-1B worker will not adversely affect the working conditions of similarly employed U.S. workers. | Hours, shifts, and benefits cannot be quietly worse for the H-1B worker or for the workers around them. |
| No strike or lockout | No strike, lockout, or work stoppage is underway in the occupational classification at the worksite when the LCA is filed. | The employer cannot place an H-1B worker at a worksite where such a dispute later arises in the same classification. |
| Notice | The existing workforce has been told about the filing, through the union or by posting, as the regulation requires. | A defective or missing notice is one of the easiest violations for DOL to find — and the hardest to fix after the fact. |
Step 1: get the wage right before you touch the form
The wage decision comes before the filing, and it is where most LCA trouble starts. Two inputs decide it: the occupation and the place of work.
First, classify the job honestly. The Standard Occupational Classification (SOC) code must match the work the employee will actually do, not the internal job title and not the most convenient code. A software role described as analyst work, or an analyst role dressed up as engineering, will produce the wrong prevailing wage — and a wage that does not match the real job is the classic reason an LCA draws scrutiny later, even if DOL certified it.
Second, set the required wage. It is the higher of two figures: the actual wage the employer pays other workers with similar experience and qualifications doing the same job, or the prevailing wage for that occupation in the area of intended employment — roughly, the metropolitan area or normal commuting distance around the worksite. DOL encourages employers to obtain a prevailing wage from the National Prevailing Wage Center, but it does not require it; employers may also use the OFLC wage data for the occupation and area. The wage level (I–IV) that comes out of this step is covered in full, with worked examples, in the H-1B Salary Database Guide. What matters for the filing is this: the wage on the LCA must be at least the required wage, for the right occupation, in the right area. Get any of those three wrong and the rest of the filing is built on sand.
One timing rule belongs here, not later: an LCA must not be submitted more than six months before the employment start date. Filing early does not buy a head start — it buys a rejection.
Step 2: file in FLAG, field by field
LCAs are filed electronically through the FLAG system. The only exceptions are employers with physical disabilities or without internet access, who must first get special permission from the OFLC Administrator to file the paper Form 9035 by mail. For everyone else, the workflow is the same six steps, and the order matters — the notice step cannot be skipped or done out of sequence.
- Employer information. The legal employer name and address as registered — the petitioner, not the client, files the LCA, even for third-party placements.
- Occupation and SOC code. The job title and the SOC code that matches the actual duties, plus the full-time or part-time basis and the hours or hours range.
- Wage. The offered wage (at least the required wage from Step 1), the prevailing wage, and its source. A wage below the required wage is a defective filing on its face.
- Employment period. The start and end dates of intended employment. The LCA cannot be filed more than six months before the start date, and the employment period cannot run past the LCA's validity.
- Worksites. Every physical location where the work will actually be performed — city, state, and county or postal area as the form requires. This is the field employers most often under-fill, and it is the subject of the next section.
- Attestations and submission. The four attestations, the notice confirmation, and the employer's signature. Once submitted, the employer can track status and retrieve the certified LCA in FLAG at any time.
DOL reviews within seven working days for completeness and obvious errors or inaccuracies. Read that sentence twice: the review is deliberately narrow. DOL does not verify that the job is a specialty occupation, that the worker is qualified, or that the wage is genuinely the market rate. A certified LCA is proof that the form passed a completeness check — not that the underlying case is strong. USCIS makes the substantive decision later, and it reads the LCA closely when it does.
Every worksite case, decided
The worksite section is where good filings separate from expensive ones. The rule underneath all of these cases is one sentence: the LCA must cover the area of intended employment where the work is actually performed, and the wage must match that area.
| Case | What to file | Notice still required? |
|---|---|---|
| Single worksite | One LCA listing that worksite and its wage. | Yes — at that worksite, before filing. |
| Multiple worksites | List every worksite on the LCA, each with its own prevailing wage where areas differ. | Yes — at each worksite. |
| Remote or home worksite | The home address is a worksite and must be listed, with the wage for that area. | Yes — electronic notice to employees in the same classification satisfies it; a home office does not excuse notice. |
| Third-party client site | List the client site as the worksite. The employer files, not the client, and stays responsible for wage and conditions. | Yes — at the client site, or electronically to the affected classification. |
| Move within the same area | No new LCA, if the new site is within the same area of intended employment and the job terms are unchanged. | Yes — post the existing LCA notice at the new site. |
| Move outside the area | New LCA for the new area, plus an amended petition before the move (see the amendment section). | Yes — full notice for the new filing. |
| Short-term placement | No new LCA, within strict day limits (see below) — and only for H-1B, not H-1B1 or E-3. | Yes — notice at the short-term site as described below. |
Short-term placement deserves its own paragraph because it is the most misused exception in the program. Under the regulation, an employer may place an H-1B worker at a worksite outside the LCA's listed area without a new LCA for up to 30 workdays in a one-year period. The limit stretches to 60 workdays only where the worker keeps a dedicated workstation at the permanent site, spends substantial time there during the year, and lives near the permanent site rather than the short-term one. During any short-term placement the employer must keep paying at least the required wage from the permanent worksite's LCA and must cover the worker's actual lodging, travel, and meal costs for every day of the placement — workdays and non-workdays alike — without deducting them from pay. The one-year period is the calendar year or the employer's fiscal year, whichever the employer chooses, and a workday is any day the worker performs any work in the short-term area. Past the limit, there is no grace: a new LCA and an amended petition are required before work continues there. And the exception cannot be used in an area where the employer already holds a certified LCA for the occupation.
Posting notice, in full
The notice requirement is the fourth attestation, and it is also the one employers most often treat as an afterthought. Treat it as a filing of its own, with its own deadline, content rules, and evidence file.
Which route applies
| Route | How it works |
|---|---|
| Union (bargaining representative exists) | Give notice to the bargaining representative for the occupational classification in the area of employment, with the number of workers sought, the classification, the wages offered, the employment period, and the locations. |
| Hard-copy posting (no union) | Post the notice in at least two conspicuous locations at each place of employment where any H-1B worker will be employed — whether the employer or someone else owns or operates the site. It must be large and visible enough for workers in the classification to easily see and read it. |
| Electronic notice (no union) | Use a means ordinarily used to tell employees about job vacancies or promotions: an intranet or electronic bulletin board, a newsletter, or email. Individual direct notice, such as a single email to each affected employee, counts once and does not need a 10-day run. |
What the notice must say
Whether union, hard-copy, or electronic, the notice must state that H-1B workers are sought, how many, in which occupational classification, at what wages offered, for what employment period, and at which locations — plus that the LCA is available for public inspection at the employer's principal place of business in the U.S. or at the worksite, and the complaint statement: that complaints alleging misrepresentation of material facts in the LCA, or failure to comply with its terms, may be filed with any office of the Wage and Hour Division of the Department of Labor.
Timing, proof, and what goes wrong
The notice must be given on or within 30 days before the LCA is filed. A notice posted after filing is late, and a notice posted two months early is stale — both fail the attestation. The posted or bulletin-board notice runs for 10 days. Keep proof as if DOL will ask for it, because DOL does: the dates the notice ran, the locations or addresses it was sent to, a copy of the notice itself, and — for a union route — evidence the representative received it. That proof goes in the Public Access File.
Two failure modes deserve emphasis. First, a notice at the wrong site: notice must go to workers in the occupational classification at the place of employment, not to a general company bulletin nobody in that classification reads. Second, a new worksite added after filing: if a worker is later placed at a site the LCA never contemplated, notice must be given to workers at the new site on or before the day the worker starts there. Employers that move workers first and post later have already broken the sequence.
Certification, denial, and correction
Three outcomes are possible, and only one lets the case move forward.
- Certified. DOL found the form complete with no obvious inaccuracies. The employer can now file Form I-129 with USCIS, with the certified LCA as evidence. Certification is not an approval of the job or the worker.
- Denied or returned for errors. The form was incomplete or contained an obvious inaccuracy. There is no appeal that fixes a bad form — the remedy is a corrected filing, which restarts the seven-working-day review clock. Budget for that restart in any start-date planning.
- Certified, then challenged. A certified LCA can still draw a complaint or an investigation if the attestations were false — a wage below the required wage, a worksite never listed, a notice never given. Certification never cures a false attestation.
The denial causes practitioners see most often are unglamorous, which is good news — they are all preventable: a wage below the required wage for the area; a SOC code that does not match the actual duties; a worksite county that does not match the wage area; a worksite missing from the form entirely; an employment period that starts within the six-month window problem (filed too early) or runs past what the LCA can cover; and a notice step skipped or documented nowhere. A denied LCA blocks the petition outright: without a certified LCA, there is no I-129 to file.
Validity and amendment triggers
A certified H-1B LCA is valid for up to three years — but the end date written on the LCA controls, and the employment period in the petition cannot run past it. When the job changes, the question is always the same: does this change need a new LCA, an amended petition, both, or neither?
| Change | What is required |
|---|---|
| Worksite move outside the area of intended employment | New LCA for the new area, plus an amended or new petition filed before the move. This is a material change, and the worker can generally begin at the new location once the amended petition is filed, without waiting for approval. |
| Worksite move within the same area | No new LCA and no amendment, if the job terms are unchanged — but post the existing LCA notice at the new site. |
| Substantial change in duties or occupation | Amended petition, and a new LCA if the occupation or wage basis changes. A title change alone, with the same actual work, usually is not material — the test is the real duties, not the label. |
| Full-time to part-time, or the reverse | Generally an amended petition, because hours change the wage obligation and the terms USCIS approved. |
| Short-term placement (30/60 workdays) | Neither a new LCA nor an amendment, within the day limits and conditions above — but notice at the short-term site still applies. |
| Pay raise within the same job and area | No new LCA is needed to pay more than the LCA wage; the LCA sets a floor, not a ceiling. |
The governing rule is that an amended or new petition must be filed before a material change takes effect, with a new certified LCA where the change requires one. Filing after the worker has already moved or already changed roles is the failure mode that turns an ordinary update into a compliance case. Note the sequence carefully: the new LCA must be certified before the amended petition can be filed — the amendment depends on the LCA, just as the original petition did.
LCA vs petition: two decisions, not one
Confusing the LCA with the petition is the root of most misunderstandings about this process. They are decided by different agencies, on different questions.
| LCA (DOL) | Petition (USCIS) | |
|---|---|---|
| Question asked | Is the form complete, and are the wage, conditions, and notice attestations in order? | Is this a specialty occupation, is the worker qualified, and is the employment real and as described? |
| Review depth | Completeness and obvious errors, within seven working days. | Full adjudication, including evidence and, where needed, a request for evidence (RFE). |
| What it grants | Nothing by itself — no status, no work authorization. | If approved, the classification that lets the worker work and seek status. |
| How LCA errors surface | As a complaint or investigation into the attestations. | As an RFE or denial when the petition does not match the LCA — wage, worksite, or duties that drifted from the certified filing. |
The practical consequence: never treat a fast LCA certification as a signal that the petition is safe. The fastest LCAs are often the ones nobody read carefully — and USCIS reads them carefully later.
After certification: what the employer still owes
Certification is the middle of the employer's obligations, not the end. Three duties run for the life of the employment.
Keep the Public Access File
The employer must maintain a Public Access File containing the certified LCA, the worker's rate of pay, a description of the actual wage system, the prevailing wage rate and its source, documentation of the notice given to workers, and evidence that the H-1B worker received a copy of the LCA. The file is kept at the employer's principal place of business in the U.S. or at the worksite, and it must be made available to any interested party who asks. A file assembled after a complaint arrives is not a file — build it as the case proceeds, and keep it for the full retention period the regulation sets.
Give the worker a copy
The employer must give a copy of the LCA to each H-1B worker no later than the date the worker reports to work. This is a small step with an outsized audit footprint: it is one of the first things DOL checks, and its absence is easy to prove.
Live by the attestations
Pay at least the required wage for every pay period, at every worksite on the LCA. Do not place the worker at a worksite where a strike or lockout is underway in the same occupational classification. Do not let duties, hours, or worksites drift from the certified filing without going through the amendment analysis above. And remember the complaint route printed on every notice: any interested party can bring an LCA complaint to the Wage and Hour Division, and a willful violation can bring back wages, civil penalties, and debarment from the program.
Common mistakes, fixed
| Mistake | Why it hurts | Fix |
|---|---|---|
| Wrong SOC code | Wrong prevailing wage; petition mismatch on duties. | Classify from actual duties, not the internal title; re-check the code before every filing. |
| Wage below the required wage | Defective on its face; wage liability from day one. | Take the higher of actual wage and prevailing wage for the correct area, every time. |
| Worksite county vs wage area mismatch | The wage belongs to a different area than the work. | Match each worksite to its own area and wage before submitting. |
| Missing worksite | Work at an unlisted site is uncovered work. | List every physical site, including home offices and client sites; use the amendment or short-term rules for later moves. |
| Notice posted late, or nowhere provable | Failed attestation; complaint-ready evidence gap. | Run notice inside the 30-day window, keep dates, locations, and copies in the Public Access File. |
| Filed more than six months early | Rejected timing, lost weeks. | Count back six months from the start date and file inside it. |
| Public Access File built late or thin | The first thing an investigation asks for is the thing you do not have. | Open the file when the LCA is filed; add each document as it is created. |
Frequently asked questions
How long does LCA certification take?
DOL reviews LCAs within seven working days for completeness and obvious errors or inaccuracies. That is a review deadline, not a merits decision — and a filing returned for errors restarts the clock when the corrected version is submitted.
How long is a certified LCA valid?
A certified H-1B LCA is valid for up to three years, but the end date written on the LCA controls, and the employment period in the petition cannot run past it. A new period of employment needs a new LCA.
What is the difference between the LCA and the H-1B petition?
The LCA is the employer's attestation filing with the Department of Labor, covering wages, working conditions, no strike or lockout, and notice. The petition is Form I-129 filed with USCIS, which decides whether the job is a specialty occupation and the worker is qualified. The certified LCA must come first; the petition cannot be filed without it.
Does a certified LCA guarantee USCIS approval?
No. Certification means only that DOL found the form complete with no obvious inaccuracies. USCIS adjudicates the petition separately and can issue a request for evidence or deny it — including where the petition does not match the certified LCA on wage, worksite, or duties.
What must the posting notice say, and how long must it stay up?
The notice must state that H-1B workers are sought, how many, in which classification, at what wages, for what period, and at which locations, plus that the LCA is available for public inspection and the Wage and Hour Division complaint statement. It must be given on or within 30 days before filing. A posted or bulletin-board notice runs for 10 days; individual direct notice, such as a single email to each affected employee, counts once. Union workplaces give notice to the bargaining representative instead.
Do I need a new LCA if the worker moves to a new worksite?
It depends on the move. Within the same area of intended employment, with unchanged job terms, no new LCA is needed — but post the existing LCA notice at the new site. Outside the area, a new LCA plus an amended petition filed before the move are required. Short-term placements outside the area need neither, but only up to 30 workdays in a year (60 where the worker keeps a workstation and ties at the permanent site), with the required wage and travel and lodging costs covered.
What goes in the Public Access File?
The certified LCA, the worker's rate of pay, a description of the actual wage system, the prevailing wage rate and its source, documentation of the notice given to workers, and evidence that the H-1B worker received a copy of the LCA. Keep it at the principal U.S. office or the worksite, make it available to any interested party who asks, and retain it for the full period the regulation sets.
What happens if the LCA is denied?
The petition cannot proceed without a certified LCA, so a denial stops the case at DOL. The fix is a corrected filing addressing the error — wage, occupation, worksite, or notice — which restarts the seven-working-day review. Common causes are a wage below the required wage, a SOC code that does not match the duties, and a worksite missing or mismatched to its wage area.
