You can enter the U.S. before the date of expiry of the visa provided you have not exceeded the number of entries allowed by the visa. the length/duration of your stay has nothing to do with the date of expiry of your visa, but with the type of visa. For example if your visa expires on Aug. 01, 2009, you can enter the U.S. anytime before Aug. 01 and stay in the U.S. beyond Aug. 01 as long as you meet other requirements of the visa.
Does the Indian visa work in the same manner?
