Update: I went this morning to Chaeng Watthana and it is quite far from sukhumvit. I didn’t have an appointment and the wait was about 30 mins to speak to an officer. Another 15 mins or so to get my passport back. They didn’t ask for a TM30 either.
They were advertising e-extension for TR visa EVERYWHERE. On their website you can submit the required docs and schedule your appointment beforehand and pay the extension fee (+additional service charge since it’s 3rd party). I imagine this is useful for people who just want to come in and get out asap. Overall about an hour of my time.
Do I need to book an appointment for an extension on a TR visa or can I walk in?
Which office is best for this? I normally go to Chamchuri Square for previous visa things. Is there a better location?
