i had my interview sept 29, 2010 but unfortunately i wasn't issued a visa because my father became u.s citizen prior my interview. i was asked to file a letter for child status protection act(CSPA) for me to retain my f2b category together with cenomar(i just submitted one from a C.O but i was asked for another copy so i needed to run for N.S.O again) and my fathers certificate of naturalization after about two weeks i recieved the aprroval notice of my CSPA then i proceeded to the embassy for the thought that ill be paying for the visa mail at air 21 at the embassy, after i submitted my passport and the aproval letter unfortunately i was adviced to go home and just wait for their response thru mail because the C.O that requires my document still needs to review my papers again. i was just wondering if they will send me may passport together with the visa or letter for another appointment schedule and for how long will i wait for the letter to arrive? will someone pls enlighten me regarding my case i'm so stressed out don't know where to seek advice pls help...
