My husband has been waiting now for 5 years and still no citizenship. We contacted a lawyer a year ago, they pretty much just wrote letters and couldnt get anything done, so we are in the process of getting a refund. We have contacted another lawyer but she needs the paper stating he had an interview on such and such date and passed, but I unfortunately lost it. So she wanted us to get that document from USCIS via a FIOPA. Our previous lawyer filed for one a few months back and we're still waiting. Our lawyer cannot file the lawsuit without the document. So my question is, how long does it usually take to receive our requested documents?
