So for reasons in life I don't need to explain right now I filed I-751 5 years late (don't judge, seen a case here that filed 10 yrs late and got approved) my case was accepted, finger prints were used again and I received a 24 month extension letter, still waiting for the 48 month one. In this time I had to come back to my country for a medical reason, now my question is how likely am I to go back and be admitted with this expired card and extension letter? @mindthegap would really appreciate your opinion and to the rest please don't judge, you don't know everything I have been through, I'm just looking for an opinion/advice.
