Yes, but only if you first receive Advance Parole (Form I-131 approval). Traveling outside the U.S. without Advance Parole while your I-485 is pending will result in your application being considered abandoned, and USCIS may deny your green card.

You can travel internationally during your I-485 process if you obtain Advance Parole before departure. This travel document must be approved before you leave the U.S. Exceptions exist for applicants in valid H-1B or L-1 status, who may travel without Advance Parole, but this only applies under specific conditions.

Traveling while your green card application is pending can be risky if done without proper authorization. Even with Advance Parole, reentry isn’t guaranteed especially if you have prior immigration violations or inadmissibility issues. If you're in a vulnerable category (e.g., asylum, TPS), travel should be considered carefully with legal guidance.
