Hi all,I filled my AOS on the June 28,2011 and i received the 3 letters of receipt(I-130,I-485,I-765) and FP appointment letter 2 days ago .when i read the papers on the I-130 and I-765 everything is correct but on the FP appointment letter and the I-485 notice my zip code is not correct.it should have been 20866 instead of 20899.what should i do now?just call and let them know there is a mistake or do i need to send a new I-485 with the correct zip code?they scheduled me to take my FP on Aug 2,Will this delay the process time? Do they need to send me a new appointment letter with the correct zip code or cant i just explain to ASA people there so they can overwrite it?

sorry for the lengthy questions.

thanks
