回複：加拿大 LANDING QUESTIONS

1. Either way is fine. Don't surrender I-94 if by air.
2. No trouble, no record.
3. Should open, but better check before you go.
4. No difference.
5. Passport with previous visa, no matter what category it is, no matter it's still valid or not, valid I-94, valid I-20 for F1, I-797 for H1.
