Interview time was 7:15. Fiancee arrived about 6:30. Process was completed about 11:30 a.m. The room is like a large bank. The interview takes place while the fiancee is standing at one of the windows. The interviewer is behind plexiglass. My fiancee had a lot of documents to support our relationship. The interviewer (female) looked at: income tax, W2's, letter of employment and pictures. She looked closely at the pictures. None of our emails, call records, travel receipts were looked at - but one does not know what a particular interviewer might want to review.
The interviewer asked basic questions such as: Where finance works, what his job is, where he was born, names of siblings. My fiancee speaks English so the interview was in English.
My fiancee is one tough gal packed into 5' 1" so she was not bothered by any of it.
My fiancee had to wait 3 working days to get the visa and she had to pick it up at China Post which was very inconvenient for her because it was a one hour bus ride each way.
