What documents are needed to extend a 30-day visa exempt in Phuket, and is a TM 30 required?

To extend a 30-day visa exempt in Phuket, you typically need to provide an application form, a passport-sized photo, copies of the passport's ID page and entry stamp, and the departure card. The TM 30 form is required if you're on a private address; otherwise, if you're without a landlord, a power of attorney with a 10 THB tax stamp is necessary. The extension fee is approximately 1,900 THB. Phuket Immigration is noted for being organized, and if you have uncertainties, visiting early and consulting with volunteers for guidance is recommended.
