Thank you for the add. I have a question about tourist visa extension. I have a NZ passport and obtained a 30 day tourist visa at Padang Besar border(by train). Am I able to extend this without leaving the country? If so, for how long? I am staying on Koh Phangan and i see there is an immigration office on Koh samui. Any advice will be greatly appreciated!
TLDR : Answer Summary
A New Zealand passport holder can extend their initial 30-day visa exemption for an additional 30 days at an immigration office in Thailand without needing to leave the country. The nearest immigration office for this extension is on Koh Samui, which is accessible from Koh Phangan. It's recommended to bring your passport, some money for fees, and potentially a passport photo. Extensions can only be done once per entry.
