LOL yes over 1000
i think i was paranoid about how many people were refused the first try. I didnt explain on all of them, but put them in different envelopes and put important names of people listed through out my explanatory note and the events. So eg. in an envelope labelled "Wedding" i wrote a brief list of people there one the cover of it.. (some labeled in the back of the pictures) and closed the envelope. I dont think they verify too many people other than family members and your list of reference members that you put on your application
