Countdown to My Hubby's Visa Interview

INTERVIEW DATE FEBRUARY 28!!!!!!! We are excited. Hubby can't wait to get it over with (little bit of stress---everyone has it). If your first reaction is yay, he can get on a plane right after the interview, right? The answer is NOOOO. When he is approved (I'm not even saying "if") the visa will be issued about 3 business days later. I say "about" because nothing is promised. The embassy may decide to make him wait longer while they double-check our papers. They say never buy a ticket until you have the visa in your hand.

The abbreviations:
USCIS - U. S. Citizenship & Immigration Service
I-130 - form to apply to bring an alien spouse to the USA
NVC - National Visa Center
AOS - Affidavit of Support
DS-230 - the visa application
