All went well. IR-1 to USA. My wife had a 6:30AM appointment. We arrived about 6:15AM. Had our number and was in the building by 7:00AM. We were approved and finished by 10:00AM
Have your paperwork in order, make sure you filled them out properly, have all requested originals and make sure your doucuments are not out of date (NBI) etc: Relax and watch the flashing numbers.
I filed my I-130 on Oct 2........Interview Nov 27.......56 days start to finish. It could have been done in 45 days had it not been for the financial strain of 3 trips to Manila from Davao. Good Luck all.
