What documents do I need to bring for a 30-day extension request at IT Square, Bangkok, and is there an online form available?

I took a guest to IM and filled in a TM30 which was filed. Then she applied for a 30 day extension. They denied it as it wasn’t in the system despite the fact that they had just given it to her and she had it in her hand.

I went to Pathum Thani immigration last week as staying near Rangsit. Took Passport copy bio page and entry stamp page . Downloaded TM7 and filled in printed and signed. Passport photo attached to TM7 . Copy of TM30 downloaded from registration website . Also took copy of GF blue book and ID as backup and 1900 baht . Walked in to immigration. Presented documents to reception and was asked to sign 3 other forms given by the reception. Handed in Passport, all documents and 1900 baht. Waited outside for abut 20 minutes. Then called in to collect passport with extension for 30 days already stamped in .

Very easy seamless operation.

Apparently can now upload documents and make payment online and make appointment to present passport and receive extension stamp .

TM.7, STM.2 and acknowledgement of fines. Copy of your bio page and a copy of your entry stamp, a recent picture too for the TM.7, you may or may not be asked for a copy of your TM.30 so take it just incase along with 1900 baht.

I suggest either going for 8.30am and walking through and going upstairs or booking an appointment.

Then this one

It would help the guy if anybody who has done that recently could mention if TM30 is currently required at IT Square in Bangkok.

You need passport, TM30 from where your staying (some Immigration dont ask for TM30 but take to be safe) copy of arrival page stamp copy of data page 1900baht cash. TM7 form available there to complete can be found online but again some prefer their own form completed, I downloaded for extension few years ago and Bangkok wanted theirs so sat at the IO desk and did their form. There is an office to do coping there if you can not do elsewhere.

Make an appointment. Get there 15 mins early. They will give you three easy forms to complete. When you've done that, you'll be next cab off the rank and will jump the queue of walk-ins

This is a general list of requirements as each office has their own requirements. It's usually better to get the forms at the office as they have their own forms and if anything is wrong with the ones your print they'll just make you start over. Always use blue ink when filling out forms in Thailand.
