AOS was approved (or at least big red stamp marked approved) was made to file at interview at the LA district office at the end of Feb 2006 I was under the understanding that I had to submit my AP documents and EAD card, and in return I would receive a stamp in my passport. The officer said that they do not issue stamps anymore and that he did not need my EAD or AP documents to be returned. He did have me verify information to ensure its accuracy on a white form, and had me place my finger prints and sign in a small box (double sided) on another form. He had the two photographs that he required for the processing of the green card in the file. He indicated that I would receive a letter of approval in the mail, or the green card directly or he said I could recieve both. My question, what is the time line? My EAD card expires at the beginning of April and my AP documents in May and I am wondering if I need to apply for renewals.
