Do I need to report my TM30 after a visa run in Thailand?

A TM30 is required for foreigners who change their residence or stay in accommodation in Thailand. Since you will be leaving the country for a visa run and returning, it is important to check your TM30 reporting requirements. Generally, if you leave Thailand and re-enter, you don't need to re-report the TM30 at the immigration office, as it pertains to your current place of residence. However, it's advisable to ensure your friends who declared you on the TM30 update any relevant authorities of your re-entry.
