Is that right?
A Thai national can travel to US using their Thai passport. Without a visa?
I see what you mean.
I may have miss interpreted what she did as each time she left she was on her own and is out of town at the moment, believe it or not in the only small area in this country (that I know of) that has no telephone coverage, neither land line nor mobile, so I'll find out and report back when she gets to a coverage area and I can speak with her.
I'm sure she entered Thailand using her Thai passport and I'm sure she presented her U.S. passport (actually maybe both as they don't care) at the airline ticket counter when leaving Thailand and when entering and leaving the U.S. she would certainly have used the U.S. one, but I'm not sure which one she showed to the immigration officer at the entrance to the boarding gates here in Thailand. I'll have to find that one out from her, possibly you are right and she used the U.S. one there as well, only using the Thai one for entering Thailand. That would make more sense, as all her Thai ID is in her maiden name and anywhere you have to show both ticket ad ID I think the names have to match.
By the way, I was told by our lawyer that the U.S. does not officially recognize dual nationality either but they look the other way (do not enforce the law) in cases where a foreign born person marries a citizen and subsequently becomes a U.S. citizen.
