Do I need to provide proof of accommodation and cash when entering Thailand with my Thai wife?

When entering Thailand alongside your Thai wife through the Thai immigration line, the requirements for proof of accommodation and cash can vary. Many expats have reported not being asked for cash or extensive documentation if they are accompanied by a Thai spouse. However, it is advisable to carry a modest amount of cash (around $700 USD) as a precaution, especially if you have a history of frequently returning to Thailand or are on a visa exemption. Generally, those on a Non-O visa due to marriage to a Thai national encounter fewer checks. While the enforcement of regulations may vary, many travelers have successfully passed through immigration without needing to show any financial proof.
