Traveling to Puerto Rico from mainland while on AOS

[Johnny6751]

Hi folks, I am currently married to a USC and adjusting status from B1/B2 over stay. Same sex couple!

We filed back in June 2020 and I've been given the I-797C's already. No biometrics yet.

I need to do a trip to Puerto Rico and I was wondering if that's something risky to do right now as far for immigration concerns.

I have a valid driver license but unfortunately it doesn't work for me to board a plane with it as it is for driving purposes only.

I only have my passport which has no stamps whatsoever in it.

Given the fact that I am already in the USCIS systems, and flying to Puerto Rico is considered a domestic flight, I am afraid that on the way back I may be stopped and questioned about my current AOS.

I have heard that once you're boarding a plane back to the mainland CBP is all over the place.

Any thoughts? Should I just postpone this trip?

Thanks.

Puerto Rico is part of the US, it should be no different than flying to South Dakota.

Bring your I-485 receipt. I've heard that there are CBP checks when going from Puerto Rico to the states, although it's not an entry so you don't need a visa. But you need to show you are staying legally which you need your I-485 receipt for.
