I got my B1/B2 visa in 2005 but couldn't travel due to work. It is expiring in 2010. I want to travel now but my passport has only one page left and still I want to visit two more countries in same trip. Will it make any problem if I apply for a new passport and get other visas on new one. My U.S. visa will still be in old passport??? Will that make any difference?? This will be my first visit to U.S. so I need to clarify. Thanks.
