I was just looking at the US Consulate site and saw this in the frequently asked questions:
I am a dual U.S. and Canadian citizen and I don't have time to get a U.S. passport. May I enter the U.S. with my travel document showing my Canadian (or other) citizenship?
No, U.S. law requires U.S. citizens to enter and depart the U.S. documented as U.S. citizens. Improperly documented U.S. citizens may be barred or delayed considerably at a port of entry.
I've been traveling to the States no problem for years and have never been asked about having US citizenship as I was born in Canada. If I have an American Citizen Born Abroad certificate do I fall under this category? I've had it since 1993. I would only be applying for my first American passport on October 3 and there's no guarantee it will come before October 17th when I'm set to leave.
