Interview went good. Standard procedure. The line of questioning was exactly as expected:
1) Where does the fiance live?
2) What does he do?
3) What state?
4) What city?
5) How'd you meet?
6) Got pictures of the engagement ceremony.
7) Point out a few folks on one of the pictures.
8) Where do his parents live?
etc.
The officer was friendly. All the answers were given spot on. At the end the officer said everything looks good. Kept the passport and got the 221g green form stating a wait time of 2-6 months. Welcome to Administrative Processing!
