Thank you for the reply. I filed on 4/14 (within the 90 days) and need to travel by air within the USA next week. Going won't be a problem but coming back my card will have expired. So I did make an appt for Monday. The thing I was unsure of was wether or not I could travel without the 1 year extention reciept (within the USA) and with my expired green card. Anyway, I shall update what happens at the InfoPass appt on Monday. Tha k you once again. For taking time to reply!As long as you timely filed I-751 (they received it before your GC expired), you are in valid status. The receipt will likely come before you leave in a month. If you haven't gotten your receipt shortly before you leave, you can try to go in to an InfoPass appointment and have them give you an I-551 stamp; they should be able to verify that your I-751 was received.
