回複:加拿大返簽美國預約求助(nvars)
Just for your reference. I scheduled online at Jan 31, 2006 for an appointment on April 11. Receive their comfirmation package after 10 working days.
did you print out the online comfirmation letter? or do you have the reference number? If you have the reference number, you have just give them a call.
hope it help and good luck
