H1B Transfer: How to Change Employers Step by Step

What Is an H1B Transfer?

Despite the name, there's no actual "transfer" mechanism. What happens is your new employer files a brand new I-129 petition with USCIS to employ you under your existing H1B status. You don't re-enter the lottery. Your remaining authorized period carries over.

H1B Portability: Start Working Before Approval

This is the part that surprises people. Under the American Competitiveness in the 21st Century Act (AC21), you can start working for your new employer the moment they file your petition. You don't need to wait for USCIS to approve it. That's H1B portability, and it's one of the few worker-friendly provisions in the system.

Requirements for portability:

• Your current H1B was lawfully approved (not just pending)
• You haven't violated your status
• The new petition is non-frivolous (genuine job, real company)
• You've been in valid H1B status for at least 1 day before filing

Step-by-Step Transfer Process

Negotiate salary, role, and start date with your new employer.

They file a Labor Condition Application with the DOL certifying the prevailing wage. LCA certification typically takes 5 to 7 business days.

The employer submits Form I-129, the LCA, and supporting documents to USCIS. Government filing fees run $2,460 to $3,060.

Once you have the filing receipt (I-797C), you can start the new job. Keep this receipt. It's your proof of valid status while the petition is pending.

Regular processing takes 3 to 6 months. Premium processing ($2,805 extra) gets you a decision in 15 business days.

Risks You Should Know About

• Don't resign before the I-129 is filed. Portability protects you after filing, not before. If you quit and the petition hasn't been submitted yet, you're out of status.
• International travel during portability is risky. If you leave the country while the transfer is pending, you may need a new visa stamp from the new employer's consulate before you can return. Talk to your lawyer first.
• RFEs (Requests for Evidence) can delay approval for months. Make sure your new employer has experienced immigration counsel. This is not the place to cut corners.

Check Your New Employer Before You Commit

Use VisaTrack to research them:

• Look up their LCA filing history and approval rates
• Check their prevailing wage offers vs. actual salaries
• See how they rank among H1B sponsors
