My question is:
1. if I apply F1 visa in Shanghai, how likely I can get approval and how likely I will be turned down?
2. Is it possible for me to get visa in another place, say Mexico? I heard that I can get to Mexico without turn in my I94. Then I will be able to come back to U.S. even though I am turned down on my application of F1 entrance visa.
Thank you so much!
