回複：回複：Going to Canada during OPT

Thanks for your advice. I do understand that leaving the state during OPT is very risky if you want to re-entry. However, Canada seems to be an exception, because so many people have claimed that no visa required while re-entry from Canada within 30 days, no matter during F1 (regular) or F1 (OPT). Do you guys agree?

Many thanks!!
