I am no longer in Thailand. And as a dual citizen I have the right to legally use any of my passports when traveling. With my passport that I have not yet entered Thailand with, I also require a visa (outside of Thailand) to enter the country. When applying for a visa, it is possible to indicate that I have another passport. The fact that I am already listed in the Thai database and it is connected to the other passport is ok. I am not banned from the country or restricted from entering. And applying for the new visa is also a tourist visa, with entry by air - late this year. So, everything is legal and lawful. I just want to double check to see if anyone has had this experience (not an assumption, it's not relevant).
