Changing Jobs on H-1B: The Transfer Guide

You can start a new job the day your H-1B transfer petition is filed. Here is how portability works, what your new employer needs, and the full timeline.

Job SearchApril 14, 20268 min read

1You Don't Have to Wait for Approval

The single most important thing about changing jobs on H-1B: you can start working for your new employer the day the transfer petition is filed with USCIS. Not the day it's approved. The day it's filed.

This is the AC21 portability rule, and it changes everything about how H-1B holders approach job changes. Without it, you'd be stuck at your current employer for 3-6 months while USCIS processes the new petition. With it, the transition can happen in a matter of weeks.

The requirements are straightforward. You must be in valid H-1B status when the new petition is filed. The new employer must file a complete I-129 petition with USCIS. And the new role must qualify as a specialty occupation. That's it. Once the receipt notice arrives (usually a few days after filing), you're legally authorized to work for the new employer.

  • AC21 portability lets you start working once the transfer petition is filed
  • You don't need the approval notice to begin the new job
  • You must be in valid H-1B status at the time of filing
  • The new petition must be properly filed (complete I-129 with supporting documents)

2What Your New Employer Needs to Do

Your new employer handles the filing. Here's what that involves.

First, they file a new Labor Condition Application with the Department of Labor for the new position. This certifies the wage, work location, and job title. LCA processing takes about 7-10 business days.

Once the LCA is certified, their immigration attorney prepares and files Form I-129 with USCIS. This is the actual transfer petition. It includes your credentials, the new job offer, the certified LCA, and evidence that you're in valid H-1B status.

The new employer doesn't need to wait for your current employer to do anything. They don't need permission from your current company. They don't need your current I-129 approval notice (though having a copy helps). They file independently.

3The Timeline

1

LCA Filing: 7-10 Business Days

The Department of Labor processes Labor Condition Applications in about 7 business days. Your new employer's attorney files this first. No action needed from you during this step.

2

I-129 Preparation: 1-2 Weeks

The attorney gathers your documents (passport, current I-797, degree transcripts, pay stubs) and prepares the petition. You'll need to provide these promptly. Delays here are usually on the employee side.

3

Filing + Receipt: 3-7 Days

Once filed, USCIS sends a receipt notice within a few days. This receipt is your authorization to start working for the new employer under portability. Keep a copy.

4

USCIS Decision: 15 Days (Premium) or 3-6 Months (Regular)

Premium processing guarantees a decision within 15 calendar days for an additional fee of $2,805. Regular processing takes 3-6 months. Most transfer candidates opt for premium processing to reduce uncertainty.

Here's a realistic timeline for a standard H-1B transfer.

4Realistic Total Duration

Total from "I accepted the offer" to "I can start the new job": roughly 3-5 weeks with premium processing, depending on how fast the LCA clears and the attorney prepares documents.

5What Happens to Your Old Petition

When you leave your current employer, their H-1B petition for you is no longer valid. They can (and usually do) submit a withdrawal to USCIS, but even if they don't, the petition effectively dies when the employment relationship ends.

This is fine. Your new employer's petition replaces it. You don't need the old petition to remain active.

One scenario to be aware of: if your transfer petition is denied after you've already left your old job, you're in a tricky spot. You'd have a 60-day grace period to find another employer to file a new petition, change to a different visa status, or depart the US. This is why premium processing matters. A 15-day decision window is a lot safer than waiting 3-6 months.

6Managing the Risks

H-1B transfers are routine. Thousands happen every month. But there are a few things you should do to protect yourself.

  • Don't resign until the new petition is filed. Specifically, wait until you or your attorney have the USCIS receipt notice in hand. Filing day is the earliest safe point to give notice.
  • Use premium processing. The $2,805 fee (paid by the employer) is worth the certainty. A 15-day decision timeline versus 3-6 months of wondering is a no-brainer.
  • Keep copies of everything. Your current I-797 approval notice, all pay stubs, your LCA, your I-94 record. If anything goes sideways, these documents are your proof of status.
  • Don't burn bridges. Your current employer can't legally block your transfer, but a messy departure can cause practical problems (delayed document access, uncooperative HR for employment verification).
  • Check your I-94 expiration. Your H-1B status has an end date. Make sure the transfer petition is filed before that date, or you'll need to address the timing with your attorney.

7Finding a New Employer Who Will Sponsor the Transfer

The good news about transfers: they're easier for employers than initial H-1B petitions. No lottery. No cap. The employer can file any time of year, and there's no random selection process. You're already in H-1B status. The new employer is just picking up where the old one left off.

That makes the conversation with recruiters much simpler than a first-time H-1B petition. You're not asking "will you sponsor me through the lottery?" You're saying "I'm already on H-1B and need a transfer, which is a straightforward filing."

ShouldApply shows H-1B filing history for every company in the system. Companies that have filed transfers before are the best targets. They already have immigration attorneys on retainer, a process in place, and budget allocated. Check the H-1B company pages to see which employers have active filing histories, or use the H-1B Sponsorship Checker to look up specific companies.

ShouldApply flags companies with active H-1B filing histories. Find employers who've sponsored transfers before.

Frequently Asked Questions

Yes. Under the AC21 portability rule, you can begin working for the new employer as soon as the transfer petition (I-129) is filed with USCIS and you have the receipt notice. You don't need to wait for approval.

The full process (LCA filing through USCIS receipt) typically takes 3-5 weeks. LCA processing is 7-10 business days, petition preparation is 1-2 weeks, and USCIS issues a receipt within days of filing. With premium processing, a final decision comes within 15 calendar days. Regular processing takes 3-6 months.

No. H-1B transfers are cap-exempt. If you're already in H-1B status, the transfer can be filed at any time of year with no lottery or annual cap restrictions. This is one of the biggest advantages of transferring versus getting a first-time H-1B.

If the transfer is denied after you've left your previous employer, you have a 60-day grace period. During that time, you can find another employer to file a new petition, change to a different visa status (like B-1/B-2), or make arrangements to depart the US. This scenario is rare but worth planning for. Premium processing minimizes this risk by getting a decision within 15 days.

No. Your current employer has no legal ability to block or interfere with a transfer petition filed by another company. They can withdraw their own petition after you leave, but that doesn't affect the new petition. The transfer process is entirely between you, your new employer, and USCIS.
