I have a pending I-485 and already have my advance parole approved 3 months ago, I also have travel plans back to my country with my husband for 2 weeks and made these plans more than 1 month ago. This weekend I got notice saying my I-485 has been sent to the california service center and from what I see here that could mean Im approved for the green card without interview and seems most people are approved this way within 2 to 4 weeks. Im traveling in 3 weeks from now.

My question is what will happen if Im approved for the green card while Im out of the country? will my AP still be OK? I will take my notice with me saying my papers were sent to california.

Or what happens if I get an approval notice just prior to my trip, say 3 days before but I dont have the physical green card yet? I heard there is a stamp for your passport but not all offices will give one my office is new york city. can i still use the the AP to travel, i dont want to losse my plane tickets and other parts of the trip are paid for.
