My friend is going to Cambodia from Thailand. He like take his Thai girlfriend with him. She not have passport. Can Thai citizens travel to Cambodia without passport, only with ID.?
TLDR : Answer Summary
In general, Thai citizens are required to present a passport for entry into Cambodia, regardless of whether they are traveling by air or land. While there was previously an allowance for limited travel using an ID card for border provinces, this option has been revoked for Cambodia. Those who need to travel must obtain a passport, which can be processed quickly in Thailand. Additionally, comments suggest that using an ID card may only permit limited travel within specific districts of neighboring countries like Laos and Myanmar under certain conditions.
