I currently have an e visa that has given me 90 days. I'm currently staying in Phetchabun at a Muay Thai bootcamp. I will have to leave before my time runs out due to my visa ending, and I wish to stay in Bangkok to see my friend for some time, so I need to extend by a month. Do I have to leave the country to do so, or can I visit my local government complex in Phetchabun?

First Non-o extension questions. I arrived in Thailand Nov 1 and have a 90 day non-o stamped in until 29th Jan. My Thai spouse and I aren't married yet but we have an 8 year old daughter so I planned to do my first extension based on Thai child. 400k has been in the bank in my name a long time already so ok there. I have printed a TM7 already. Phetchabun will be the office I am applying at does anyone have the latest checklist or info on exactly what docs are required. If possible I would like to get as much ready so hopefully dont need to make multiple trips as it's 100klm away. Im 43 so wont be a retirement extension. Any info is much appreciated and thanks in advance. Dave

Went up to immigration in Phetchabun today to file TM 30 in person . I asked about having to file again if took a vacation inside Thailand stayed at a hotel then came back to the house . She said yes would have to
