Fellow Sajhaites,

I'm currently on OPT and waiting results from my H1b this year. Is it safe for me to travel to Puerto Rico??? My student visa has expired but have a valid passport and US drivers license. Do I need my passport or is US DL is enough to travel to Puerto Rico and return w/o any immigration hassel. do we even have to go through immigration if PR is "technically" part of US???

highly appreciate your help!
