My sister got an RFE, and she needs to prove her presence here on June 15th, 2012. She will send an affidavit signed and "written" by the father of the girls she was babysitting that entire week (he is U.S.C.). However, since he is a construction worker, my mom told me it would be better if I wrote the affidavit, since he might not have enough knowledge about that stuff (-___-), and have him sign it and notarized. Problem is, I have never written one and don't know what an affidavit for USCIS would look like. Could any of you tell me specifically what to write on it?
