yes there's a lot to be learned here
the PCC i am referring to should be issued by the place you visited...i remember two Post June 26, 2010 applicants who also visited US for 5 mos, i think her name is beau, the other one i forgot, they were later requested to submit fingerprint clearance...in your case, as i've stated before, they will inform you if they still need anything...just be prepared for it...
re: fingerprints (f), i think they were able to have their f. scanned at nbi...there's another agency here w/c has biometric f. scanning aside from nbi, its dfa and the other one is the US embassy...
