U.S. Customs and Border Protection will happily reply to emails explaining exactly what I said is what in fact happens. You don't have to travel to Arizona or Texas to see it first-hand.

Rather than constructing an imaginary straw man detached from reality, please try to reply to the comment and the facts with external links to refute the information. I'm more than happy to provide further counter-factual information to whatever hifalutin nonsense is offered, as if this isn't a statement of fact.

What I'm describing is what actually happens today for the overwhelming majority of border crossings. :)
