"The State Department has even issued recommendations that if you can use another country's passport to do so rather than your American issued passport."

Not when you're going to America, they don't. This guy was planning to travel to the USA. As a US citizen, with a British passport, because he let his US passport expire while he was outside the USA.

If you plan on going to Israel, and to Saudi Arabia, maybe using another country's passport for the trip to Israel might be a good idea (actually, it would be). But not to the US.

"Not when you're going to America, they don't. This guy was planning to travel to the USA. As a US citizen, with a British passport, because he let his US passport expire while he was outside the USA."

Actually he was planning on landing in Houston and continuing to Mexico without leaving the airport and depending on how Houston Intercontinental is set up I would guess without leaving the International Terminal.

Again I ask why MUST he use an American passport, what is the reason for the rule?
