Concurrent H-1B

You have an H-1B job you like, and a second opportunity just landed: a side role, a startup you want to build, or a part-time research position. The question is whether you can take it without putting your status at risk. 

You can, through concurrent H-1B employment, but only if each employer files its own petition correctly and the timing lines up. This matters more than ever right now, with U.S. Citizenship and Immigration Services (USCIS) issuing Requests for Evidence (RFEs) on roughly 8 percent of H-1B petitions in fiscal year 2024 and scrutiny rising since. 

This guide walks through how concurrent H-1B works, what each employer must file, when you can start, and how to stay compliant. It is not legal advice.

Concurrent H-1B vs transfer vs amendment

Concurrent H-1B is an arrangement where you hold valid H-1B status with one employer and a second employer files its own petition so you can work for both at the same time.

Each job stands on its own petition. One approval does not stretch to cover another company, which is the single most common misconception about how this works.

It helps to separate three terms that often get blurred together. A transfer moves you from one employer to another. An amendment updates a material change with the company you already work for. Concurrent employment adds a second job while the first one keeps running.

Before you plan around concurrent employment, clear up the assumptions that trip people up most often:

• One petition covers every job: It does not. Your existing approval authorizes work for that employer only, so a second company has to file separately for you.
• A second role must match your main field: It does not have to. The concurrent position only needs to qualify on its own and match your credentials, even if it sits in a different industry.
• You have to tell your current employer: Immigration law does not require it. The second employer must know your status to file, but informing the first is your call, not a legal duty.

Common scenarios for concurrent H-1B employment

Most H-1B visa holders who add a second job fall into one of a handful of patterns, and the pattern you choose shapes how much scrutiny your petitions draw. The cleanest setups pair one anchor job with a lighter second commitment, and the common arrangements break down as follows:

• Full-time plus part-time: This is the most common arrangement. You keep one role at full-time hours, typically 40 per week, and add a second at part-time hours, which generally means fewer than 35.
• Two part-time roles: You can split your week across two part-time positions. There is no regulatory minimum number of hours for part-time employment under H-1B, which gives you room to structure the split sensibly.
• Cap-exempt plus cap-subject: You might hold a role at a university or a nonprofit research organization alongside a position at a private company. This combination has its own rules, covered below.
• Remote or multiple worksites: You can work remotely for more than one employer, but each Labor Condition Application (LCA) and petition has to reflect the actual work location.
• A company you own: A startup you founded can be the second employer, as long as it is a real business that can act as your employer and pay the required wage, not a shell created to hold a petition.

‍

Immigration officials do not cap how many hours you can work across jobs, but they can question arrangements that look unrealistic. Two full-time positions adding up to 80 hours a week will draw harder questions than one full-time and one part-time role.

Eligibility and requirements for concurrent H-1B

Your eligibility rests on a few conditions that each have to hold for the entire period you work both jobs. Miss one, and the second position, not the first, is what falls apart. The requirements are:

• You must be in valid H-1B status: Concurrent employment builds on the status you already hold. If your primary employment ends, the foundation under the second job goes with it.
• Each employer needs a properly filed petition: The second job runs on its own approved or properly pending petition. You cannot rely on the first employer’s approval to authorize the second.
• Each job must be a specialty occupation: Both roles have to require at least a bachelor’s degree in a related field, and you have to be qualified for each one.
• Each position needs a certified LCA: The second employer files its own LCA with the Department of Labor, committing to meet the wage requirements, including the prevailing wage (the standard pay for the role in that area).
• Your hours and dates have to be credible: The combined workload and the start and end dates across both petitions need to be feasible and consistent.

What each employer must file

Your second employer, often labeled Employer B in immigration filings, runs the same process your first employer (Employer A) already did. Nothing about the petition is lighter because you already hold status. The steps below happen in order:

1. Certify an LCA with the Department of Labor: Employer B obtains a certified Labor Condition Application for the specific role, wage level, and worksite. Filing cannot move forward until this is in hand.
2. File the petition selecting “New concurrent employment”: Employer B submits Form I-129 (Petition for a Nonimmigrant Worker) and checks the box for new concurrent employment, which signals this is an additional job, not a transfer.
3. Include job-specific evidence: The petition needs a detailed job description, proof you meet the specialty occupation requirements, and evidence the company can pay the offered wage. Generic descriptions and thin documentation are what invite questions.

Each H-1B petition is judged on its own merits, so the strength of your first approval does not carry over. Employer B has to make a complete case from scratch.

Timing: when you can start the second job

Your start date with the second employer is one of the most misunderstood parts of the process, so it is worth getting precise. Two paths exist, and the safer one depends on your tolerance for risk.

Under H-1B portability, you can begin working for the second employer as soon as USCIS receives a non-frivolous petition, before it is approved. The receipt notice, Form I-797, is your evidence that the petition was filed. If the petition is later denied, you stop working for Employer B and continue with Employer A without disruption.

The more conservative route is to wait for the approval notice before starting. Relying on concurrent H-1B portability lets you start sooner, but it carries the risk that a denial unwinds work you have already begun. Many people in lower-risk situations start on the receipt; those who want certainty wait.

Concurrent H-1B processing time tracks the same timelines as any other petition, which can run several months under standard processing. Premium processing shortens that to a decision within 15 business days.

As of March 1, 2026, premium processing costs $2,965, paid on Form I-907, and it is available for concurrent filings. If your current status is close to expiring, the second employer can file the concurrent petition alongside an H-1B extension.

How the H-1B cap affects a second employer

Your biggest worry about a second job is often the cap, and the good news is that it usually does not apply. Once you have been counted against the H-1B cap, a second employer’s petition does not go back through the H-1B lottery, and that employer can file for you at any point in the year.

The distinction that matters is between two employer types. A cap-subject employer is a standard company whose petitions count against the annual limit. A cap-exempt employer, such as an institution of higher education, a nonprofit research organization, or a government research organization, can file outside that limit.

This is where one combination catches people off guard. If your primary job is with a cap-exempt employer, you can take a concurrent role with a cap-subject employer without going through the lottery, even if that second company is normally cap-subject.

The catch is that your eligibility for the cap-subject role depends on keeping the cap-exempt job. Leave the cap-exempt employer, and the cap-exempt H-1B advantage disappears, which can mean the cap-subject employer has to win the lottery to keep you.

Important note: A 2025 presidential proclamation added a $100,000 payment to certain new H-1B petitions. As of mid-2026, it applies mainly to petitions for workers who are outside the United States without a valid H-1B visa.

The agency has said it does not apply to petitions approved as a change of status, amendment, or extension for someone already in the country in valid status. The rule is under active litigation, so confirm the current position on the USCIS proclamation page before any filing.

Staying compliant while you work concurrently

Your compliance job does not end when the second petition is approved. It runs for as long as you hold both roles, and the details below are where small slips become status problems:

• Keep each I-9 and onboarding aligned with authorized dates: Each employer completes its own employment paperwork, and the dates have to match what the petitions authorize.
• Make sure your duties match each petition: The work you actually do should track the job description that was filed. Drifting into different duties can undercut the basis the petition was approved on.
• Keep records for each employer: Hold on to offer letters, pay records, job descriptions, and any employment contracts for both jobs, so you can document each role if asked.
• Think through travel before you go: Re-entry can require valid H-1B visa stamping for the employment you are returning to, so plan international trips around your petition status.
• Never work outside authorized coverage: A gap where you work without a valid petition is unauthorized employment, and a status violation can follow you through every future application.

Costs, processing, and handling RFEs

Your second employer carries most of the filing costs, and the total depends on company size and whether you add premium processing. The table below covers the fees that typically apply to a concurrent petition for someone already counted against the cap.

Because you were already selected and counted in a prior year, a concurrent filing generally skips the $215 H-1B registration fee and the lottery entirely. That removes the biggest source of uncertainty from the second petition.

RFEs in concurrent cases tend to cluster around a few issues: whether the second role is truly a specialty occupation, whether the employer can pay the wage, and whether the hours across both jobs are realistic.

The strongest response is specific and prompt, with the exact evidence requested and a clear explanation. As one practical advantage, Lighthouse includes Request for Evidence responses at no additional charge, which matters when a second petition draws extra scrutiny.

It also helps to know how three outcomes differ. A denial means the petition was not approved, so you stop the second job but keep the first.

A revocation cancels an approval that was already granted, often when the job ends. A withdrawal is when the employer itself pulls the petition. Each ends your authorization for that specific job, not your underlying status with the other employer.

Common mistakes that cause denials or delays

You can avoid most concurrent employment problems by steering clear of a short list of recurring errors, each of which is straightforward to prevent:

• Assuming one petition covers multiple employers: Every additional employer has to file its own petition. There is no shortcut around this.
• Mismatched start dates: When the dates on the petition and your actual work do not align, you create gaps or overlaps that raise questions.
• Wages, worksites, or duties that do not match the filing: If the wage, worksite, or duties drift from what was certified, you expose both the petition and your status.
• Skipping employer-specific documentation: Reusing thin paperwork from your first job invites an RFE. Each petition needs its own complete evidence.
• Working after coverage ends: Continuing a second job after its petition is denied, revoked, or withdrawn is unauthorized work.

When to talk to an immigration attorney

You do not need a lawyer for every concurrent filing, but some situations carry enough complexity that professional review pays for itself. Talk to an immigration attorney when any of these apply to your case:

• A cap-exempt plus cap-subject combination: The dependency between your two jobs creates risk an immigration attorney can help you map before you commit.
• Tight deadlines or overlapping work periods: When timing is unforgiving, small mistakes have outsized consequences.
• A history of RFEs, denials, or a complicated status timeline: Prior issues tend to resurface, so it helps to address them proactively.
• Multiple worksites or major changes in duties: Unusual work arrangements draw more scrutiny and benefit from careful structuring.

Conclusion

Concurrent H-1B gives you room to add a second role or build something of your own without leaving the job that anchors your status. The mechanics are simpler than they look: each employer files its own petition, each job stands on its own, and your dates have to line up. Get those right, and two jobs is a lawful path.

How Lighthouse helps with concurrent H-1B filings

Coordinating two petitions at once means two Labor Condition Applications, two sets of job evidence, and dates that have to line up with the status you already hold. Lighthouse prepares H-1B petitions for both candidates and the employers hiring them, with attorney review included in every case.

Because applications are prepared in under 3 weeks, you can add a second role without a long stretch of uncertainty about your start date. The team keeps worksites and dates consistent across both petitions, which is exactly where these cases tend to go wrong.

Frequently asked questions on concurrent H-1B

Can I work for two employers at the same time with H-1B?

Yes. Concurrent H-1B employment lets you work for multiple employers at once, as long as you stay in valid status and each employer files its own petition for its position.

Do I need separate H-1B petitions for each employer?

Yes. Each employer files its own petition and its own certified LCA. Your first employer’s approval authorizes work for that company only, so a second company has to petition separately.

‍Can I start working for the second employer as soon as the petition is filed?

Under H-1B portability, you can begin once USCIS receives a non-frivolous petition, before approval. Starting on the receipt carries the risk that a denial unwinds work you have already begun, so some people wait for the approval notice instead.

Does concurrent H-1B count against the H-1B cap again?

No, not if you were already counted. Once you have been counted against the cap, a second employer can file for you at any time without going through the H-1B lottery again.

What if my second employer’s petition is delayed or denied?

You continue working for your first employer without disruption. If the concurrent petition is denied, you stop the second job, but your status with the original employer stays intact.

Is concurrent H-1B allowed if one employer is cap-exempt?

Yes. If your primary job is with a cap-exempt employer, you can take a concurrent cap-subject role without the lottery. Your eligibility for the cap-subject job depends on keeping the cap-exempt position.

Do I need to update anything with my employers to stay compliant?

Keep each employer’s I-9 and onboarding aligned with your authorized dates, and make sure your duties match each petition. If your hours change with an existing employer, that employer may need to file an H-1B amendment.
