Hi Folks,
I am about to graduate in a month or so. My F-1 VISA has been expired but recently received a 'post-completion' catogory OPT authorization. As a next move, I have been offered a job recently in a school here in US that would last almost a year. Work related travel is a part of the job. So, here is a help seeking question.
1. What documents do I need to arrange to get a new VISA stamp on my passport ?

Note: school has issued a new I-20 which is good for one year.

Thanks for your suggestions.
