Hi guys, I finally received the interview letter! But I have a concern because I am a full time student and are not able to work full time (Just started tutoring, making about 1k) and my wife who is USC and petitioner for my I-130 and I-485 can't work due to our new born baby. I have provided my uncle as Affidavit of Support, who makes about $70,000 year. We use my father's credit card for groceries (bless them =) ). Could you guys give me some inputs and advice on my situation? Thanks in advance!
