As I have already applied for status change b1 to f1, and result are still pending ,I have applied extent ion today, 8th Nov is last day for my stay in USA, what are the chances, and are there any other way I can stay back here?
You are in status while your application is pending . Do not forget to apply for immigration lottery.
You should not have filed the B-1 extension after you filed the COS to F.
You should talk to an attorney about the wisdom of going home for the F stamping.
