My status:
1. F1 changed from F2 in USA in year 2001, now I am a valid F1.
2. Want to attend a conference in Toronto this July
3. I have beed rejected for my F2 application in Shanghai in year 2000
Is it ok if I re-enter USA without a new VISA? I have "application recieved" stamp in my passport, is it a problem?
Thanks
