Sleepy... a search of the forums seems to indicate that this interview is the one to get your 2 year green card. I would take all the "proof of relationship" with you that you can.
Lami, we did the interview and apparently we need to have another medical done, so we have just a month to send this in. I had already gone in today just after the interview, all went well at the interview,
I have to return back to the doctors on Thursday and than after the TB test is checked the rest of the medical will take place, it cost us $270 altogether.
