I encourage you to sign a petition I have drafted at the request of our community urging the Obama Administration to reinstate reissuance of nonimmigrant visas (including work visas like H-1, student visas like F-1, and family visas) within the USA, a practice that was discontinued in 2004. If the petition receives 100,000 on-line signatures by February 23, the Administration will review it, send it to the appropriate policy experts in the administration, and issue an official response. Signing the petition takes only a few minutes.
I have two more years to complete a Ph.D. with a valid I-20, but my Visa expires in August 2013. I want to visit India in June-July 2013. If I come back in July, do I need to apply for F-1 visa (and F-2 visa for my family) extension? Would I have problem in reentry if I have one more month of valid F-1/F-2 visa?
You will need a new visa only if you return after August 2013. Check with your DSO to make sure you have all the appropriate requirements completed.
Thank you for the help that you offered through the 'Resume Review' service. I truly apreciate your time and the directions that you gave me.
