From VJ. com... "IR-1 / CR-1 Spouse Visas are immigrant visas issued to foreign spouses of US Citizens. After the US citizen spouse files (and has approved) the proper petition with the USCIS, the foreign spouse will complete the visa process completely outside the US. Upon approval and once issued, the foreign spouse may enter the US with their visa and pass through the arrival Port of Entry, where they will become a Permanent Resident immediately." (
As mentioned - VisaJourney.com is a great source of info - including current timelines per/location. I would suggest you NOT travel during the next few weeks (or, until you are notified). My wife and I were out of the country, and had to return when we got notice for an appointment.
Tried it twics about ten years ago - during the first attempt, the computers were down at the embassy and they just told her flat out “no” to keep the line moving. Second time - the embassy worker doing the interviewer told her to “give up”, and that she would “never go to the U.S.”. Bout a year later, she came on a K-1 - been married almost nine years now.
