Can I work for two employers at the same time on H1B?

Yes — this is called concurrent H1B employment. It requires each employer to file a completely separate H1B petition (Form I-129) with USCIS, along with a separate LCA for their specific worksite. You cannot begin working for the secondary employer until USCIS approves their petition. Once both petitions are approved, you can work for both employers simultaneously.

Does the secondary employer need to go through the H1B lottery?

No. Once you have been counted against the H1B cap (whether regular cap or advanced degree), you are cap-counted for life. Any subsequent H1B petition filed on your behalf — including a secondary concurrent employer's petition — is not subject to the cap or lottery. The secondary employer can file at any time during the fiscal year.

Can I work for the secondary employer while their petition is pending with USCIS?

No. Unlike an H1B transfer (which benefits from AC21 portability allowing work upon receipt), a new concurrent employer petition does not carry portability benefits. You must wait for USCIS to approve the secondary petition before you begin working for that employer. Premium processing is strongly recommended to minimize this wait.

What if one employer is full-time and one is part-time — is that allowed?

Yes, and this is the most common structure. The primary employer typically employs you full-time (40 hours per week); the secondary employer hires you part-time (10–20 hours per week). Both LCAs must accurately reflect the actual hours. The secondary employer's LCA must show a part-time arrangement with wages proportionate to the prevailing wage for those hours.

Can I have two full-time H1B employers both claiming 40 hours per week?

In theory, the regulations do not impose a total hour cap across all concurrent H1B positions. However, this raises serious credibility concerns with USCIS — a person cannot realistically work 80 hours per week across two demanding specialty occupation roles. Both LCAs must accurately reflect the actual hours you work for each employer. Overstating hours on an LCA could constitute a misrepresentation.

Can I be self-employed or start my own business while on concurrent H1B?

No. H1B self-employment is not permitted. You cannot file an H1B petition for yourself, and you cannot be your own employer. The concurrent employment rules apply only to two or more third-party employers who each independently employ you. The employer must have the right to control and supervise your work — an arrangement you cannot satisfy as a sole owner of your own company.

If one of my employers fires me, what happens to my other H1B?

If your primary employer terminates your H1B employment, you enter the 60-day grace period. Your secondary employer's separate H1B approval is not automatically affected by the primary's termination — but the secondary may not have been a full-time position. You would need to quickly either find a new primary employer, transfer to the secondary as your new primary, or change status. Consult an immigration attorney immediately.

Do I need two separate Form I-9s?

Yes. Each employer must independently complete a Form I-9 for you. For the secondary employer's I-9, you would present your passport, your I-94, and the secondary employer's I-797 approval notice as the employment authorization document. The secondary employer cannot rely on the primary employer's I-9 — each employer has an independent obligation to verify employment eligibility.

Concurrent Employment

H1B Multiple Employers: Concurrent Employment Guide

You can work for two or more employers simultaneously on H1B status — but each employer must file a completely separate H1B petition. Here is everything you need to know about concurrent H1B employment, from filing requirements to payroll implications.

Legal: Yes, with separate petitions

Cap: Not required for secondary employer

Work Start: Only after approval

The Short Answer: Yes, But Each Employer Files Separately

The H1B visa does not limit you to a single employer. Under 8 CFR 214.2(h), an H1B worker may hold multiple simultaneous H1B statuses — one for each employer — provided that each employer independently files a Form I-129 petition with USCIS and obtains their own approval. This is known as concurrent H1B employment.

The key distinction from an H1B transfer is that concurrent employment involves two separate, simultaneously active H1B petitions — not a transfer from one employer to another. Your primary employer's H1B authorization does not extend to your secondary employer's work. Each employer must go through the full H1B petition process, including obtaining a certified LCA from DOL, completing Form I-9, and filing the I-129 petition.

The most important limitation: you cannot work for the secondary employer until USCIS approves their petition. Unlike an H1B transfer (where you can begin work once USCIS receives the petition under AC21 portability), a concurrent employment petition does not carry portability rights. For the official process details, see the USCIS H-1B Specialty Occupations guidance.

Common Use Cases for Concurrent H1B Employment

Software Engineer at Tech Company + Part-Time Researcher at University

Primary H1B

Full-time SWE at a tech company (40 hrs/week)

Secondary H1B

Part-time researcher at a university (15 hrs/week)

University is cap-exempt — secondary petition can be filed any time, no lottery needed. Both LCAs must reflect actual hours and wages.

Professor with Industry Consulting Agreement

Primary H1B

Tenured professor at a university (full-time)

Secondary H1B

Technical consultant at an AI startup (10–15 hrs/week)

Very common. University typically files primary H1B; startup files secondary. Both must be specialty occupation positions.

Medical Researcher + Clinical Practice

Primary H1B

Research scientist at a medical center

Secondary H1B

Part-time physician at a private clinic

Both require separate LCAs at each worksite. Both must pay at least the prevailing wage for each role separately.

Consultant on Project Basis — Two Client Companies

Primary H1B

H1B from staffing agency placed at Client A (full-time)

Secondary H1B

H1B from Client B directly for a specific project (part-time)

Complex — if staffing agency is primary petitioner, Client B must file their own H1B. Hours must be clearly delineated.

Filing Requirements for Concurrent H1B Employers

Separate I-129 Petition

Each employer must file their own Form I-129 with USCIS. There is no combined or joint petition form. The primary employer's approved I-129 does not cover the secondary employer.

Separate LCA (ETA-9035E) per Employer

Each employer files their own LCA with DOL before filing the I-129. The LCA must list the actual worksites where the employee will work for that specific employer, the prevailing wage, and the hours.

Separate Form I-9 at Each Employer

Each employer must complete and retain a Form I-9 for the employee. The I-797 approval notice from each employer serves as the employment authorization document for that employer's specific position.

Accurate Hours on Each LCA

Each LCA must reflect the actual hours the employee will work for that employer. If combined hours exceed 40, both LCAs must still accurately reflect each employer's allocation. USCIS reviews whether each position is a bona fide full-time or part-time specialty occupation.

Prevailing Wage for Each Position

Each employer independently must pay the prevailing wage for the specific occupation and worksite listed on their LCA. The secondary employer's wage cannot be discounted because the employee already has income from the primary employer.

Separate Attorney Engagement

The primary and secondary employers will typically each engage their own immigration attorney. The petitions are completely independent filings — one employer's attorney should not file on behalf of another employer.

Payroll, W-2s, and Tax Implications of Concurrent H1B

Concurrent H1B employment creates a dual-income situation with independent payroll obligations. According to DOL H-1B program requirements, each employer independently must pay the prevailing wage listed on their LCA.

Category	Primary Employer	Secondary Employer	Notes
Tax Forms	W-2 from Employer A	W-2 from Employer B	Two separate W-2s at year-end. File combined on personal tax return.
Social Security & Medicare	Withheld by Employer A on their wages	Withheld by Employer B on their wages	No cap coordination between employers — both withhold independently.
Federal Income Tax Withholding	Withholding based on Form W-4 at Employer A	Withholding based on Form W-4 at Employer B	Consider adjusting withholding or making estimated tax payments to avoid underpayment penalty.
Benefits (Health Insurance)	May be offered by primary employer	Generally not offered by secondary (part-time)	No requirement for secondary employer to offer benefits if part-time.
LCA Wage Compliance	Must pay at least prevailing wage listed on LCA A	Must pay at least prevailing wage listed on LCA B	Each LCA wage is independent. Both employers audited separately by DOL.
H1B Cap Status	Uses the cap-counted slot	No additional cap slot needed — cap already counted	Secondary employer's petition is cap-exempt if worker already used cap lottery.

Concurrent H1B Timeline: From Offer to Authorization

Weeks 1–2

Secondary employer decides to hire; confirms H1B concurrent employment structure with immigration attorney

Weeks 2–3

Secondary employer files LCA on DOL FLAG system for their worksite. Wait for DOL certification (~7 business days).

Weeks 3–4

Secondary employer's attorney prepares I-129 petition with certified LCA, support letter, degree verification, offer letter

Weeks 4–5

I-129 filed with USCIS. Premium processing available ($2,805 for 15-day adjudication). Cannot begin work for secondary employer until approved.

Weeks 5–8

USCIS processes petition. With premium, decision within 15 business days. Without premium, 3–5 months standard.

Upon Approval

I-797 received. Employee completes Form I-9 at secondary employer. May begin working. Both employers now active simultaneously.

H1B and Self-Employment: Still Not Allowed

Concurrent H1B employment requires two legitimate third-party employers, each with the right to supervise and control your work. You cannot use concurrent employment as a workaround for self-employment. Owning an LLC and filing an H1B from that LLC — where you are the sole owner and operator — does not satisfy the employer-employee relationship requirement. USCIS will look at whether the petitioning employer exercises actual control over your work. If you are both the owner and the primary worker, that is self-employment, and H1B is not designed for that structure. See our for more details.
