I am currently a full-time worker on OPT. My OPT expires this coming May. I would like to go back to my country for vacation during X'mas break. Lots of people says leaving the US on OPT status is risky. Is that really true? I think if I am not employed, that is true. But I have a full-time job. Should I be able to re-enter without risk? Please let me know. Thank you.
