When do I need to report my residential address to police after arriving in Thailand on a non-B visa for work?

After arriving in Thailand with a non-B visa, you must report your residential address within 24 hours. This process primarily involves the landlord or you filing the TM.30 form at an immigration office. Although late reporting can result in a fine, many expatriates have shared that not reporting may not cause issues when exiting Thailand, but it could affect future visa extensions or reports if you cannot provide proof of address registration.
