There is lots of information on the timeline to the AOS interview. My husband and I had our AOS approved in LA on February 27th, 2006. Aproval letter, green card are to come in the mail. No stamp in my passport but our file was definitely marked approved. My question: From the time of approval of the AOS when should the letter and/or green card arrive? When should we begin to get worried? I appreciate that the LA office is one of the busiest, but any experiences from other DO would be helpful.
