I have the H1B visa stamped in my passport but soon my passport will be expiring. When I obtain a new passport do I again have to get the visa stamped from an U.S Consulate outside U.S or will my existing visa still be valid and I just have to carry my old passport alongwith the new passport during travel outside U.S
