Thanks Pasi and mark. I got the AOR yesterday. Should I send the supporting docs also to Buffalo along with complete application form or should I wait to hear from Buffalo as a next step. Thanks...
It is not a choice, you must submit the full application with the supporting documents to Buffalo visa office as soon as possible before your 120 days elapse, Buffalo will not contact you if they do not receive your application and supporting documents except after 120 days to inform you that your application has been refused because you have not sent anything before the deadline.
Hurry up man, do not waste your time.
