Thank you for a very detailed breakdown of the process. I am waiting for CEAC to review documents I submitted for my mother's IR-5 case. If you know and don't mind answering few questions, did you have to do medical in Almaty? Would they accept medical from Russia? I emailed CEAC but haven't received a response on this yet.
Since you stated that they cannot mail passport to Russia, did you have to come back to pick it up?. How long did it take from interview to get passport with visa?
