Hmmm a review of Amman
I did a CR1 through there. Start to finish took a year. On stateside it was quick. On Amman's side slow.
They do answer your emails rather quickly, but it might not be the response you want.
Be prepared to take all evidence of your relationship to the interview and be prepared because they may ask for more.
The interview can be done in arabic or english. IMO do it in the language you mostly communicate in.
K1 are different than K3 or Cr1 because on K3 and Cr1 they do security checks prior to interview and K1 after.
It can be difficult to get hold of the consulate on the phone. You may be on hold, so it's probably best if your husband calls.
for CR1 and K3's if you are the choice of agent. They will send you the packets and not your husband. (happen to me)
My husband had to go to the embassy and get his packet, not sure if they let you still do that. Seems like things have changed there.
Maybe JP can add some information she is the only one I know besides Reddaisy that did a K1 through Amman.

p.s there might be other things I am missing but I can't remember at the moment.
