I returned to the UK 5th Feb with my half Thai daughter. She entered Thailand on her UK passport on a 30 day exempt. We applied for her new Thai passport while in Thailand and she left Bangkok to return to UK on her Thai passport. The immigration wrote in uk passport child overstay but no charge.
all domestic flights within Thailand may it be Thai or Foreigner must have had vaccine 14 days before travel to phuket OR PCR test done 7 days before travel and then another on arrival. My friends GF has not had a vaccine and she never got any tests. Not even on arrival to Phuket. She lives in Bangkok that has high number of case's.
