i was there today, all you need is your passport, a picture of yourself, photocopies of your passport, ฿1900, and that’s it. They have the forms you need there. Make sure you fill it out in blue pen, I used turquoise pen and they made me redo it. Go to IT laksi don’t even bother going to immigration division one because they will send you to IT Laksi and you will have wasted your time. Try to go as early as you can, I got there around 9:30 bc i went to the wrong place and the line just to get a queue number took almost 2 hours. Once you get your number everything passes by quickly they didn’t ask me for a TM 30 form but it’s probably because my leasing agent already filled it out for me and submitted it. i got out around like 2:45 bc they take an hour off for lunch. bring snacks, a portable charger and something to do
