@Malcolm ****

Try with a rental contract and a Resident Certificate from Immigration instead of the Embassy.

@Stuart *****

You can register av account as a foreigner.

You add addresses seperate under your account, you will need documents from the owner for that part.

And then you register yourself at the address later.

Not a very intuitive website. But you can have your own account

@Nongnuch *******

I feel this part kinda answered what to do NOW.

---

Wherever you are staying will need to file the TM30 for you.

Everytime you sleep somewhere else, you are supposed to get a TM30 filed.

Rented accommodation is fine for visa applications.

But I guess this might have been a bit too unspecific not mentioning that the landlord of the rented home needs to supply documents.

The other part touched on the last question in OPs post.

@Stuart *****

The landlord of the rented accommodation will need to do the TM30 for you, or give you the documents required to do it yourself at Immigration or registering the address on the TM30 website so you can do it yourself there.

But rented accomodation is fine for visa application and extensions, as long as you are staying there at the time of applying. Immigration might come visit you.

@Graham *****

Yeah, I've done that now. I procrastinated it because I was super overwhelmed. Got some help with putting in the name of the owner and whatnot correct and it was smooth sailing. 😛

@Jan *****************

I will add here that whenever I've gone to Immigration ( Cha-Am, Petchabri ) to get this done personally, the Immigration officers wanted a recently dated confirmation from the landlord that they indeed was letting me do this process myself. I didn't have a recent letter, and they still did it, but they told me next time I would have to get a updated confirmation.

Mileage may vary, but something to note.

@Nongnuch *******

Well, sure.

Might not have come across well, but that part was when their house is finished and they moved into it.

Wherever you are staying will need to file the TM30 for you.

Everytime you sleep somewhere else, you are supposed to get a TM30 filed.

Rented accommodation is fine for visa applications.

The last part I'm not clear on, but assuming it will technically be your wife who would need to do it. But you can make a account online for yourself and adding the address yourself there, with her owner documentation, and file it all yourself when needed.

@Josh *******

As long as you can get a residence certificate you are golden.

If Phuket doesnt offer it unless you have done a 90 day report, plenty of other places that will. Take a holiday up the coast 🙂

The guidelines specifically state you need to stay in the country where you applied until the process is finished.

Doing anything else puts you approval at risk.
