I had my interview today. My appointment time was 10am. Arrived at the consulate at 9:45. It took 2 hours for my number to be called to submit original documents. They didn't asked any copies or copies of my husband document's to prove domicile. After window 2 I sat back and 5 minutes later I was called to window 7.
I was asked:
What your husband do for a living?
How did you met?
When was the first time you met in person?
When did you get married?
Do you have any children?
Have you been arrested?
Have you been to the U.S illegally?
After a few minutes he handed me the paper and told me my visa was approved.
Thank you everyone, especially to Saylin and Dwheels76.
