Is there an application form to download for the Certificate of Residence in Thailand?

The TM 30 must be applied for by whomever you rent your "residence" from. Whether that is a hotel or an individual/company from which you rent a home. they can file on-line or in person at the immigration office.

I did this two weeks ago in Ubon Ratchathani. Ignore the form on the Thai Immigration website, it is out of date and each Immigration Office has their own version.

In addition to your TM30 make sure you also take your lease agreement or Yellow Book with you.

Be careful when selecting the reasons why you want a Residency Certificate as they will issue you with separate ones for each requirement.

For example, I wanted to open a bank account; buy a car; and apply for my Thai driving licence. I was given a separate Residency Certificate for each one. Note you cannot copy them, you must use the original you get from the Immigration Office.

Also note they are only valid for one month.

Nope. Did it yesterday and she handed me new forms to fill by hand.

Find your involved immigration office in internet and see if you can download the requested TM18 from their website.

Some Immigration offices will have their own forms to fill out for this one, and not use the one available for download on the Immigration website

It's a very simple form available at Immigration. You complete your details and there are tick boxes for the reason(s) the CoR(s) will be issued.

It’s called TM18, they’ll give you this when you go there. Make sure you take your passport photos as they’ll need it to stick or the form and put a stamp on the top of the photo.

Never been asked to fill.one in
