What is the process for obtaining a 1-year retirement visa extension in Chiang Mai, Thailand?

Chiang Mai Immigration: My 1-Year Retirement Extension Experience

Yesterday I got my 1-year extension of stay based on a Non-Immigrant O (retirement) visa (NOT O-A) at Chiang Mai Immigration, near the airport. I originally entered Thailand three months ago.

First, a disclaimer: things can be different at other immigration offices, or even at the same office on another day. This is Thailand, after all, where randomness is practically an official administrative procedure. I'm simply sharing my experience in the hope it helps someone.

My timeline:

06:00 – Arrived at Immigration, exactly 10 days before my current permission-to-stay stamp expired. There were already around 20-25 people in the live queue outside the booth. Some people were sitting on chairs, with friends or relatives holding their places.

06:45 – They started handing out queue numbers.

07:00 – Got number B16 and sat down to fill in the four required forms.

08:20 – Document checks started. There were two groups:

- People who had submitted their documents the previous day in the collection basket. They were called by name. This group was processed in about 30 minutes.

- New applicants like me, who had received their queue numbers that morning, were called by number.

08:55 – My number was called. I was asked to correct three things and return to the same window without joining the queue again:

- Copies of the relevant bank book pages had to be printed in the correct size. There's a copy shop around the corner.

- One of the forms, STM.2, had to be replaced with a newer version.

- I had to sign the eVisa form using a blue pen.

09:30 – Documents checked and accepted! I was given a new queue number, 959, for the immigration officer interview. I was told to return to the main building at around 13:30.

13:15 – Back at Immigration.

14:30 – My number was called. They collected all my documents, checked everything again, took the 1,900 THB fee, and told me to sit down and wait again. 🤦

15:10 – Called in for a photograph.

16:00 – Finally! Exactly 10 hours after arriving, I received my 1-year extension of permission to stay in Thailand.

But I wasn't quite done.

Immediately afterwards, I went through another round:

- Another queue number.

- A couple more document copies.

- Another document check.

- Another queue number.

- Another photograph.

- Another 3,800 THB fee.

- Another queue.

This was for the Multiple Re-Entry Permit, and took approximately one additional hour.

A few practical tips:

1. Bring a laptop. There is Wi-Fi, and you'll have plenty of time to use it.

2. Bring something to eat and drink.

3. Bring some extra cash for photocopies and unexpected expenses.

4. Have patience. Seriously. A LOT of patience.

5. Double-check your forms and document copies, but be prepared for something to need changing anyway.

That's it. A long day, but I got everything done independently, without using an agent.

I'm happy to answer any questions about the process or the documents I submitted. Hopefully, my experience will save someone a little time and frustration!
