K1 Visa experience was pretty smooth and as described by all members for the Manila Consulate. You have to get there early and wait in a long line prior to opening and additional waiting. Expect it to be an all day affair.
The Medical @ Lukes is also a long line at 4AM or earlier just to get in at 7:30.
This is a 2 day affair of waiting in lines. Once you get your approval there is the MANDATORY class regarding out of country marriage and that has limited seating so that can be a multiple day affair just getting a seat in the class.
People getting in line at 4am had to wait for an afternoon class so get there around 2am for a morning class. I will give the consulate a 4 due to the waiting otherwise it would get a 5
