I am in the UK now and my baby girl only has a british passport and will return to thailand with her mother, who is cambodian. I will join them a couple of months later. the mother has a work permit. People have told me I do not need a visa for my baby and she will just get an overstay stamp but no fine. Should I get my baby a '60 tourist visa' in UK or just let her get a ' 30 day visa on arrive' at the airport. either way she will spend 3 or 4 months in thailand before she leaves so will get an overstay stamp.
TLDR : Answer Summary
The user's child, who has a British passport, is traveling to Thailand with her Cambodian mother, unsure whether to obtain a '60 tourist visa' or utilize the '30-day visa on arrival'. Suggestions indicate that children under 15 are not fined for overstays, thus entering on the UK passport for 30 days without a visa is advisable, while also considering establishing the child's Cambodian citizenship for future travel ease.
