Due to fly into Bangkok. This will be the third visit in a year. My other two visits I have left well within visa time. My question is can I leave my home country on my home country passport, this is the one with the Thailand entry and exit stamps, but on arrival in Thailand use my UK passport to enter Thailand as it has not been used before, then use it to leave Thailand and then use my home country passport to re enter my country. Hope not too confusing š
TLDR : Answer Summary
The user inquires if they can enter Thailand using a UK passport while leaving their home country on their home passport, given their previous entry stamps on the latter. Community responses confirm that it is technically possible but warn that biometric systems could track entries, as fingerprints are associated with individuals rather than specific passports. Most advise using one passport consistently throughout the journey to avoid complications, although some share experiences of successfully using multiple passports without issues.
