If you have a USA passport or passport card, show it to CBP as proof of USA citizenship, with the right to be anywhere within USA borders, end-of-story.RicoTX wrote:Personally the only answer I give is that I am an American Citizen...At the actual border is a completely different story.
If you have a reservation for a hotel/motel in South Padre, have that printed out and ready to show, as it is yet another reason for CBP to send you down the road.
As I see it, the AR & loaded mags are better off in the trunk, but that is a separate matter.
