ME AND MY FRIEND SENT OUR APPLICATIONS IN NORMAL USPS AIRMAIL ON MARCH 27, AND NOT YET RECIEVED FILE NUMBER. IF ANY BODY GOT FILE NUMBERS AFTER SENDING USPS AIRMAIL WITHOUT TRACKING PLEASE LET ME KNOW.
I think in the future you should not use normal mail . I sent mine from British Columbia to Buffalo on March 23rd on Canada post priority mail and I got my file # on June 3rd.
