I’m a conditional resident through marriage to a U.S. citizen. I submitted my I-751 (as a joint filing with my U.S. husband) several months ago. USCIS then sent me a long Request for Evidence, asking for more documents to prove that our marriage is bona fide, plus more financial information and so on. I think USCIS was suspicious of our case the first time around, because my husband is a lot younger than me and we’re of different religions. On top of that, he has been living in a different city for the last few months while he finishes up his degree. I’ve got a bad feeling USCIS might deny the I-751. What happens then? Can I file an appeal?
