I would like to find out some information from people who travel using 2 passports. I am finding it difficult to simply swap them at the boarder, as immigration officers always tell me it's not possible.Once I 'check out' from one country they need to 'check me in' to another country next to the stamp I just got.I am based in Thailand. Ideally ,next time, I would like to apply for Thai tourist visa with passport number 2. Where should I go? How to do it? Is it possible at all?
Many thanks for any input.
