I’m applying for adjustment of status while on a valid visa. Can I travel outside the U.S. during the process?

It's definitely possible to travel while applying for adjustment of status, but there’s a catch: You need to get something called advance parole before you leave.

While you are applying for adjustment of status, traveling outside the U.S. can complicate your case

If you’re in the middle of applying for adjustment of status, don’t leave the U.S. without advance parole
