It was ok in general but the line outside was not that organized, you just keep asking the guards which line is it because everyone of them is saying diff things. I waited an hour for my first interview with a young Filipino guy, done in 30mins, called again for biometrics after 15-20 mins. The final interview was around 9:20am with a black CO who is so formal, it only lasted for 10-15mins because he only need another cenomar and nbi with my wrongly spelled name in the birth cert. and before 10 am i was given an instruction to submit the additional docs and filled out the courier delivery address.
Was issued K1 visa on May 16,2011 a week after being reviewed by the same CO!
