I work for TCS, my visa expires on September 28, 2016. There is a change in my location now and we will file an amendment on July 15th along with h1b extension. Right now am in India, it will take a month for me to receive acknowledgement documents (Aug 15th ). I will hardly be left with one month for visa expiry, though extension is in progress. In this situation can I travel to US while extension is pending and am still left with one month visa validity. Kindly help me out.
