Thank you so much for sharing your timeline and all this information is very useful. I got DOS favorable recommendation on October 1st, but until today I have not received the USCIS decision. My lawyer said that I could start the process with the AOS, but I'm hesitant to start until I receive a final letter from USCIS. Now, nowing that it takes several months based on your experiences to file of AOS, should I start the process now? Thank you.
