I am an Indian student in the US on a valid F-1 visa (issued by US consulate in New Delhi, India). However this visa expires on 10 July 2012 and my passport is valid up to 6 Feb 2013. My I-20 is valid up to 31 May 2014. Here's my question - I have to travel to Sydney for a conference ending 6 July 2012. I would be returning back to US on 9 July 2012 (I would be at the port of entry that day). Will I be allowed to re-enter US on my existing visa/passport?
I have two reasons for asking this question - 1) My visa expires the next day that I am trying to re-enter and 2) My passport expires on the 6th month (February) from the date I am trying to re-enter (9 July 2012).
I would really appreciate your help on this issue. Thanks!
