My category which is a special refugee based category called HRIFA, doesn't have a visa wait time. In other words, visas are immediately available for that category.
That's just how long it took them to process it. It was supposed to be completed in only a year, but there was a huge delay after 9/11. So, my turned is finally up. Hopefully the interview will go well, and I'll get approved.
I'm not complaining though; I could be in the brother/sister category and the wait time for those is 10 years.
