When a foreign worker loses an H-1B job and files a B-2 or H-4 during the 60-day grace period, the goal is to remain lawfully in the United States. But when a new employer later files a change of status back to H-1B, a quiet procedural rule can create chaos. This is known as the “last action rule,” and it can instantly reverse an approved H-1B if USCIS later approves the earlier B-2 or H-4.
The Last Action Rule
When two applications for change of status are pending—such as a B-2 filed after a layoff and a later H-1B filed under premium processing—USCIS adjudicates them independently. Whichever approval notice with an I-94 is issued last controls the person’s status.
If the H-1B is approved first and the B-2 is approved later, the B-2 approval overrides the H-1B. Overnight, the beneficiary moves from work-authorized status to visitor status, forcing a halt to employment and often requiring a new H-1B filing to restore work authorization.
How It Happens
- H-1B employment ends and the 60-day grace period begins
- Worker files B-2 change of status during the grace period
- New employer files H-1B change of status under premium processing
- USCIS approves the H-1B with I-94 and the worker resumes employment
- Later, USCIS approves the old B-2 with an I-94
Result: the last action—the B-2 approval—changes the person’s status back to B-2, voiding H-1B work authorization.
Impact on Travel and Adjustment of Status
When the person later travels abroad or files for adjustment of status, USCIS or a consulate reviews their full status history. If the record shows a later B-2 or H-4 approval, questions can arise about unauthorized employment or maintenance of status.
Even if the individual sends a withdrawal letter after H-1B approval, there is no formal revocation process for an I-539. USCIS may still approve it later and issue a conflicting I-94.
Strategy 1: Request Sequential Adjudication
When filing the new H-1B, the petitioner should include a cover letter asking USCIS to adjudicate the pending B-2 or H-4 first and approve it only through the day before the H-1B start date.
Example language:
“Beneficiary has a pending I-539 seeking change of status to B-2 filed during the 60-day grace period. We respectfully request that USCIS adjudicate the pending I-539 first, approving it through November 16, 2025, and approve the H-1B effective November 17, 2025.”
This gives USCIS a roadmap to avoid overlap and documents a good-faith effort to maintain continuous status.
Strategy 2: Withdraw the I-539 After H-1B Approval
If USCIS approves the H-1B first, send a withdrawal letter for the pending B-2 or H-4 immediately. The letter should cite the receipt number, note the new H-1B approval, and request that the I-539 be closed effective the day before the H-1B start date.
Example language:
“The beneficiary has been approved for H-1B status effective November 17, 2025. Please treat this as a withdrawal of the pending I-539 and consider the B-2 status valid only through November 16, 2025.”
Keep proof of delivery as evidence of timely withdrawal.
Strategy 3: Use Consular Notification When Needed
For risk-averse cases, the H-1B can be filed for consular notification rather than change of status. The person then travels, gets a visa, and re-enters in H-1B status. It avoids the last-action problem but requires international travel.
Withdrawal and Authorized Stay
Withdrawing a pending I-539 does not automatically make the prior period unlawful. As long as the I-539 was timely filed while the person was in status or during a grace period, the time it remained pending is generally considered a period of authorized stay.
Motions to Reopen for Erroneous Approvals
If USCIS approves the I-539 after a documented withdrawal, a Form I-290B can be filed claiming service error. This is not a standard motion use and results vary. In practice, a service request or motion to reopen may correct the record, but prevention is far safer than correction.
Key Takeaways
• The last USCIS action with an I-94 controls the person’s status
• Include sequencing requests in new H-1B filings
• Withdraw pending B-2 or H-4 applications immediately after H-1B approval
• Maintain documentation of filings, approvals, and withdrawal delivery
• For cautious cases, consider consular notification to eliminate overlap risk
Final Thought
Overlapping change-of-status filings can look harmless but can lead to serious consequences months later. Because USCIS adjudications are not synchronized, even a well-intentioned B-2 or H-4 filing can unintentionally erase an H-1B approval. A deliberate sequencing plan, prompt withdrawal, and clear correspondence are the only reliable ways to protect a client’s lawful status and future eligibility.
