I entered the US as a student in Aug 2001 and had got my F-1 visa stamped as valid till 2006. After completing a Masters in 2003, I worked for a year, initially on OPT and the remaining part on a H1-B visa. I have changed my status back to F-1 and presently pursuing a PhD since Spring 2005. I plan to go to India in Summer. So, do I need to get a fresh F-1 visa stamp to be able to come back though I have a stamped F-1 visa valid till 2006 as described above?
Any help will be greatly appreicated. Thanks a million!
