Hello, me and my wife have a AOS interview for green card coming up march 10, i recently received a letter from uscis stating to bring a bunch of documents with me to interview, however, i have a problem (so i think)? they ask for all original and copy of supporting documents that we have submitted for applications and me made the mistake of no making copies and sending them all the originals!! i am freaking out because i don't have the documents they are asking for. It doesn't make sense to me since i sent them all the documents! PLEASE HELP! how can i get copies back?? thank you
