Yes.
As you will see in previous posts you require to have 15+ days remaining on your entry stamp to apply for the non O.
You require 800k in bank on day of application.
The bank can provide bank letter on day of application.
A small deposit on day of application is good idea
Here is link for appointment.
Make sure you make hard copy of confirmation email

Here is useful link.
You should make and appointment.
For my most recent (few weeks ago) they wanted a TM47 receipt and I also provided bank statements.
The previous year they were not happy with just my bankbook and photocopies of pages..
Also very detailed list by @TallGuyJohninBKK.
As someone posted earlier .... You may require an onward flight within 30 days for the airline to issue boarding pass.
One option is to use companies such as "onward ticket.com"
Just have passport.
Of course bring you bank book just in case.
Some io want to see funds maintained during under consideration period.
SCB do not have branch at CW.
Most other banks do.
Myself and many others use money transfer companies.
This is covered in "banking finance" forum.
WISE is recommended.
Opening a bank in Thailand is not as simple as one would imagine.
Where will be based in Thailand
All nonsense.
You would not be stamped in for 7 days.
You are not deported.
You can be refused entry.
As pointed out already, you are kept in Detention holding rooms.
Pictures of that already posted
Perhaps this has already been mentioned.,.regarding initial steps.
The airline OR immigration press you to sign "form"
Vaguely recall that's like signing an agreement to depart and you pay for flight..
As usual you completely misread my posts.
I'm huge fan of Vietnam.
First 7 years in Thailand I went to Saigon every month.
Yesterday I applied for multi 3 month eVisa to Vietnam.
Unrelated advice to others ..the eVisa application is soooo simple.
I have read couple of posts from ubonjoe regarding this.
I have never read a post of someone doing that.
Naturally most of us mugs are not familiar with what ubonjoe outlined.
What's your point.
Vietnam suits some and not others..
Same as Philippines.
Same as Cambodia.
Some people love those joints some dislike.
So back to the OP ...the tax issue is nonsense.
