What document do you need to bring if travel out of US for a month?
1. Passport got stamped, haven\'t received card yet. You don\'t have to have the actual card to enter US, the passport stamp is valid too, right?
2. Also does anybody know what form you need to fill out and submit when coming back to US as a PR? I heard you don\'t need I-94 card any more. How do they keep track how long you stayed in US and how long you travelled out?
