No, as far as I could remember, the other 14 applicants I am with did not present their NBI nor CENOMAR. They are not required for individual or group counseling. The only thing I discovered was that if applicant's petitioner had been divorced before, they would need to present a photocopy of his divorce decree or just know the divorce date. If you failed to do so, they will not release your certificate on that same day and will put it on hold till you get to submit the required pertinent documents. The only thing I submitted for registration was my 2 photocopies of my 2 valid ID with photos in it (bring the original IDs as well) and the registration form they provided. For the individual counseling, the facilitator only asked for my photos.
Registration Fee is for Php 400. I just had my CFO seminar last Tuesday and received my visa last Friday. You can check my experience at this link: http://k1visaapplicant.wordpress.com/2013/07/13/cfo-guidance-and-counseling-part-1-and-visa-pick-up-at-2go-sm-mall-of-asia/
