The travel trap explained: when leaving the U.S. converts your COS to consular processing, Canada and Mexico brief trip risks, and travel freeze guidance for FY2027
If you're an F-1 student selected in the FY2027 H-1B lottery and your employer is an H-1B-dependent company (50/50 threshold), there's a critical question: does leaving the United States between petition filing and October 1 trigger the $100K fee? The answer involves understanding the difference between change of status and consular processing — and a potential travel trap.
| Scenario | $100K Fee Risk | Recommendation |
|---|---|---|
| Stay in U.S., COS approved, no travel | NO RISK — COS exempt | Safest approach |
| Travel before COS approved (any destination) | HIGH RISK — COS abandoned | Do NOT travel |
| Brief trip to Canada/Mexico before Oct 1 | HIGH RISK — reentry may require CP | Do NOT travel |
| Travel after October 1 (H-1B active) | Need H-1B stamp; may need CP | Get stamp at consulate when ready |
| Employer NOT 50/50 (fee doesn't apply) | NO RISK regardless | Travel as normal for COS timing |
When your employer files an H-1B petition with a Change of Status request, USCIS processes both the petition approval and the status change together. If you leave the United States while the COS is pending, you are considered to have abandoned the COS request. The petition itself may still be approved, but your status change is voided.
To actually activate your H-1B status, you would then need to go to a U.S. consulate abroad, get an H-1B visa stamp, and enter the U.S. through consular processing. At a 50/50 employer, this conversion from COS to CP could trigger the $100K fee — because the petition is now effectively a consular processing case.
This applies even to brief trips. A weekend trip to Toronto, a family emergency in Mexico, or a connecting flight through a foreign country that requires clearing immigration — all of these could potentially abandon your COS. Automatic revalidation (the rule allowing brief trips to Canada/Mexico without a new visa stamp) applies to existing visa status, not pending COS requests. The safest approach: stay in the United States from the day the petition is filed until October 1, 2026.

However, traveling while COS is pending still abandons the COS request — meaning you'd need a visa stamp to reenter. This is a timing inconvenience, not a fee issue.
Automatic revalidation allows holders of certain expired visa stamps to reenter the U.S. from Canada, Mexico, or adjacent islands without a new stamp. However, this applies to people in valid status — not those with a PENDING change of status. If your F-1 status is extended via cap-gap but the COS hasn't been adjudicated yet, relying on automatic revalidation is risky and should be discussed with your attorney.
Consult your immigration attorney immediately. Options may include: requesting expedited processing of the COS, filing a motion to preserve the COS despite travel, or accepting that the COS will be abandoned and planning for consular processing. If your employer is not 50/50, the fee concern is eliminated. If they are 50/50, the attorney may need to evaluate whether the $100K fee applies to your specific situation.
Once your H-1B status is active (October 1), you can travel — but you will need an H-1B visa stamp in your passport to reenter the U.S. If you haven't gotten a stamp yet (because COS doesn't provide one), you'll need to schedule a stamping appointment at a consulate. This is a normal process, not related to the $100K fee. Most H-1B workers schedule stamping during their first international trip after activation.
