What email do you have for them?
I just sent the e-mail through their website like everyone else. I talked to the guy when I went to resubmit my fingerprints for L1 and he said they've had alot of people have to re-do their fingerprints for some reason. The first time I never got a confirmation e-mail after my L1 appt but I did this time... makes me wonder if the guy who did them ever submitted them to ISP.
