H-1B transfer between employers in 2026.

An H-1B transfer is a new employer's H-1B petition; portability may allow the worker to begin after USCIS receives a nonfrivolous petition if statutory conditions are met. The term "H-1B transfer" is not a legal term — it is the common way of describing a new H-1B petition filed by a different employer for a current H-1B worker. The new employer must file a new Form I-129, obtain a certified Labor Condition Application from the Department of Labor, and demonstrate that the job qualifies as a specialty occupation requiring a US bachelor's degree or higher.

The key advantage of being a current H-1B worker is that you are not subject to the H-1B cap when changing employers. If you were previously counted against the H-1B cap (selected in the lottery and approved), any subsequent H-1B petition filed by a different employer is not subject to the cap. This means there is no lottery wait and the new petition can be filed at any time during the year. Cap-exempt employers (universities, nonprofit research organisations, and government research organisations) are also exempt from the cap for their initial H-1B petitions.

The portability rule under INA 214(n) allows you to start working for the new employer as soon as USCIS receives the new petition, without waiting for approval. This rule applies if you were lawfully admitted as an H-1B nonimmigrant, have not been out of status, and have not engaged in unauthorized employment. If the new petition is ultimately denied, your work authorization ends immediately on the date of denial, and you must stop working for the new employer. Some employers prefer to wait for approval before allowing you to start, particularly if the new role involves a different job classification or industry.

Current H-1B workers who have received a job offer from a new US employer and need to understand the transfer process, timing, and risks. This guide is for workers who are comparing the portability option (start on receipt) with the safer option (wait for approval), and for workers who have been laid off and need to find a new H-1B sponsor within the 60-day grace period.

This guide is also for employers and HR professionals who are hiring a current H-1B worker and need to prepare the LCA and I-129 petition. Employers should be aware that the H-1B transfer requires the same level of documentation as a new H-1B petition — the job must qualify as a specialty occupation, the employer must demonstrate ability to pay the offered wage, and the employee must have maintained valid H-1B status.

New employer documents: The new employer must file Form I-129 with USCIS. Supporting documents include a certified Labor Condition Application (LCA) from the Department of Labor, which the employer files through the DOL's online LCA system. The LCA must be certified before the I-129 is filed. The employer must also provide a detailed job description, an organisational chart showing the reporting structure, evidence of the employer's ability to pay the offered wage (annual report, tax return, or audited financial statement), and a company profile showing the employer is a real operating business with an established presence in the US.

Employee documents: The H-1B worker must provide: the most recent Form I-797 approval notice from the current H-1B employer, the most recent Form I-94 (print from the CBP website), recent paystubs from the current employer covering at least the last 2 to 3 months, a copy of the passport bio page and all visa stamps, copies of all prior H-1B approval notices and I-94s to show continuous maintenance of status, educational credentials (degree certificates and transcripts, and if the degree is from outside the US, a course-by-course evaluation from a recognised credential evaluation service), and a professional resume showing the qualifications for the specialty occupation role.

Maintenance of status evidence: If there are gaps in employment or status, include evidence explaining the gaps. Acceptable gap reasons include the 60-day grace period after a prior H-1B ended, paid leave (maternity, medical, or personal leave approved by the employer), or time spent in another valid nonimmigrant status (such as B-2 visitor or F-1 student). A gap without a valid explanation can result in USCIS finding that the worker failed to maintain H-1B status, which would make the transfer petition ineligible for approval.

The optimal timing for an H-1B transfer is before you leave your current employer. File the new H-1B petition while you are still employed by your current H-1B sponsor. This eliminates any gap in employment and removes any question about maintenance of status. If you have already left your current employer, you have a 60-day grace period to file a new H-1B petition. The 60-day grace period starts from your last day of employment, not from the date of the termination notice or the last day you received pay.

The LCA certification from the Department of Labor takes 7 to 10 business days and must be completed before the I-129 is filed. Standard processing of the I-129 takes 2 to 5 months depending on the USCIS service center. Premium processing (Form I-907 with a $2,805 fee as of 2026) guarantees a 15-calendar-day processing time. Many employers choose premium processing for H-1B transfers because the additional fee eliminates months of uncertainty and allows the employee to start working under portability sooner. Total timeline with premium processing is typically 3 to 5 weeks from the start of the LCA process to USCIS approval.

If you file under portability (starting work on receipt rather than on approval), plan the start date carefully. You can begin working for the new employer on the date USCIS receives the new petition or on a later date specified in the petition. Confirm with your new employer's immigration team that they plan to use premium processing and that they will notify you immediately when USCIS issues a receipt notice. If the petition is denied after you have started working under portability, you lose work authorization immediately and must stop working.

The strongest H-1B transfer petitions build the case around continuity: the worker has maintained valid H-1B status (with paystubs and I-94 records showing continuous employment), the new role is clearly a specialty occupation requiring a US bachelor's degree (with a detailed job description and organisational chart), the wage meets the prevailing wage requirement (with the certified LCA matching the offered salary), and the employer can demonstrate ability to pay (with tax returns, financial statements, or annual reports showing revenue sufficient to cover the salary).

The new employer's documentation is often the weakest part of an H-1B transfer petition. USCIS scrutinises new companies, small businesses, and consulting firms more closely because the employer-employee relationship can be harder to prove. If the new employer is a startup, include evidence of funding, office space, business licences, and a detailed organisational chart showing how the H-1B worker fits into the company structure. If the new employer is a staffing company or consulting firm, include evidence of the end-client relationship, the specific project the worker will be assigned to, and how the employer maintains control over the worker's employment.

The job description must map to a Specialty Occupation as defined by USCIS — the role requires a bachelor's degree or higher in a specific field, the degree requirement is common to the industry for the position, the employer normally requires a degree for the position, or the duties are so specialised that the knowledge required is usually associated with a bachelor's degree. If the job description is generic or the degree requirement is stated as "any field," USCIS will likely issue an RFE or deny the petition. The employer should state the minimum educational requirement and explain why the role requires that specific degree field.

One of the most important decisions in an H-1B transfer is whether to start working for the new employer as soon as the petition is filed (portability start) or to wait until USCIS approves the petition (approval-start). Each approach has advantages and risks. Portability start allows you to begin working for the new employer immediately after USCIS receives the petition, eliminating any gap in employment and preserving your full 60-day grace period for future use. Approval-start eliminates the risk of having to stop working if the petition is denied, but may create a gap in employment if the previous role has already ended.

Portability start is a good choice if: (1) the new employer uses premium processing, so the risk window is only 15 calendar days, (2) the new role is in the same or similar occupational classification as the previous H-1B, (3) you have strong evidence of maintenance of status (unbroken paystub history), and (4) the new employer is an established company with a history of H-1B approvals. Approval-start is a better choice if: (1) the new employer is a startup or small company with no H-1B track record, (2) the new role involves a different occupational classification from the previous H-1B, (3) you have gaps in your paystub history, or (4) you have had a previous H-1B denial or RFE.

If you choose portability start and the petition is later denied, you must stop working for the new employer immediately. You cannot switch back to the old employer without a new H-1B petition unless the old employer has not yet notified USCIS that your employment ended. The safest strategy is to coordinate with both employers so that you do not resign from the current role until the new petition is approved, or at least until USCIS provides a receipt notice confirming the new petition has been accepted for processing.

Changing employers during H-1B status is a good time to build your professional network in your new role. Seek out mentorship programs within your new organisation and professional associations in your field. Strong mentorship relationships can provide guidance on career progression, performance expectations, and navigating the transition to permanent residence sponsorship.

Networking opportunities through industry conferences, alumni events, and professional meetups can also help you discover roles and career paths you may not have considered. If your new employer has an employee resource group for international workers or a formal mentorship program, join it early. Many H-1B holders find that mentorship from colleagues who have already gone through the green card process is invaluable in understanding timelines, employer expectations, and how to advocate for sponsorship.

The H-1B transfer between employers checklist should include the status, contract, form edition, fee, deadline, address, school record, work authorization, tax residence, account term, insurance scope, or local procedure that controls the next step.

Pitfalls include starting before receipt, weak paystub history, travel while pending, job duties that do not match the SOC, and assuming transfer means automatic approval.
