File Form I-539 (or I-129 for work visas) to extend your current status while your green card is pending

Visits to countries like Iran, North Korea, or Syria can trigger extra scrutiny or delays at U.S. ports of entry.

Even with a valid visa, CBP officers can question your travel history and deny re-entry if concerns arise.

If you need to renew your visa abroad, consulates in certain countries may delay or deny stamping based on your travel record.

Always carry employment letters, recent pay stubs, and visa documentation when re-entering to avoid problems.
