ubonjoe (I could figure out how to respond to your response) Thanks for your response. She's only staying a month, so it wasn't critical that she enter as a Thai citizen. A follow up question: What does she need to renew her Thai passport? Is showing the old passport enough? Does she need to show a Thai ID (which she doesn't have), a Thai birth certificate (which she doesn't have with her), or a tambien ban (showing her residence in Thailand, which she also doesn't have because she resides in the US, but she could get registered at a relative's home). I think it cost 1000 baht. Thanks again.
