I have a US B1/B2 visa on my old passport. The old passport has a cancelled stamp on the second page. The visa is still intact with no physical damage. My new passport is of the same type and has the same name as in my old passport. I have read on travel.state.gov that it should be fine. I am a bit concerned about the 'cancelled' stamp on the old passport. The bio page on the old passport is completely legible and of course the visa is perfectly intact without any damage. Can someone tell me if I will have any issues travelling to the states?
