Any cash equivalent is fine.

You should have no issue, but every entry is up to the officer you are in front of.

No.

You can only do incountry if you have a Thai bank account.

If not enter with it.

Its a No from all.banks unless you get very lucky somehow.....

No.

Seb Gerault you can come and go many times a year still.

You CANNOT max out the 60 day stays with extensions.

You will be given 1 x30 day extension per year.

If you try a 2nd you will be given 7 days.

Then you will run into problems, you cannot live in Thailand on tourist stamps any longer.

If you are exhibiting tourist behaviors, visit and go home and come back again later in the year, no extensions... you wont likely have any problems.

Your patterns and history will be looked at.

BUT it is always up to the officer you are in front of.

Bottom line is have the correct permission of stay.

@Amit ******

NO, the law is CASH.

what an officer does is at his discretion.

If he accepts something that's an individual decision.

We are always at the mercy of the officer we are in front of.

As stated she can go to immigration and get a 1yr extension with her proof of citizenship 1900b

Or pay 1900b and get a 30 day.

Or do nothing and see if the airport will fine her on leaving, as she is Thai.

@Pascal *******

this is completely incorrect.

Currently you can enter and receive 60 days then do a 30 day extension 1 time.

If you reenter, you get 60 days and if you try and extend a 2nd time you will only get 7 days.

For a maximum of 157 days.

@Roberto *****

Bangkok Bank will not issue a "bank letter" if the funds are locked.

You will not be able to use those funds as "proof" as you do not have access to use the funds in the account.
