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.
