Does my Thai wife need to report my stay to immigration when I visit Thailand?

When traveling to Thailand and staying at a spouse's residence, it is generally required for the house owner to report foreigners within 24 hours of their arrival using the TM30 form. However, in practice, many find this requirement is not strictly enforced, especially for short stays or if one does not interact with immigration authorities. The TM30 reporting can be completed quickly, in some cases online, and should include taking necessary documents like the house registration book and the foreigner's passport to the local immigration office. Ultimately, while it's advisable to follow the law by filing the report, many expats feel it is optional for short visits.
