We got approved today. They didn't ask for affidavit of support or any other relationship evidence. The interview was only about 5 minutes. I was only asked the ff questions:
1. "How did you meet your fiance?", I explained we met on a freelancing website when my fiance hired me to help him with some software projects, consul and I even joked about how he hates the COBOL programming language.
2. "What does your fiance do?". I explained his job.
And then the consul told me to wait a few moments, and then maybe after a minute he just said I am approved and will get my visa in about 3 weeks.
