With your interview September 17th may I ask when you applied and then received preliminary approval prior to that date? There are certainly some inconsistencies in the overall processing timeline from what folks are posting here to be certain. Am I guessing that an interview date in Fort Erie was much easier to book than at Toronto, or was that a choice made on distance?

I think I unknowingly did myself a favor in allowing a solid 4 months from initial application to my first planned trip to the U.S.

Cheers!
