I believe it was A1 Passport and Visa Services in Manhattan but I'll confirm that with her. As I said, her visa was a tier 4 general student, certainly not as complicated as a marriage visa, but not without it's hurdles. Given the horror stories I have read online from various sites regarding the British Consulate in New York and their timelines, this has been a breeze, much more so than other visa's that I have helped my kids with in the past.
