The Thai citizens can enter on the US passports on 60 day visa exempt.

Once in Thailand can then get their Thai passports renewed.

There will be no overstay or fines as they are Thai citizens.

You can visit your local immigration once in Thailand and they will explain the process of staying even though they entered on a foreign PP.

It's not a problem any longer to do that.

As a UK citizen you did not need a visa for 60 days.

You will exit as your extension expires and reenter with just a tourist visa exempt stamp for 69 days.

Which you can then extend for 30 days.

Most offices prefer 1 transfer per month.

The transfer should be around the same time each month to avoid any problems.

Each office and then officer will ultimately decide.

The simpler you make it the easier to get through.

@Barry *******

you have to try and be reasonably consistent.

For example if you deposit on the 3rd and then the next month on the 28th, that is almost 2 mths between deposits.

Its not just that you deposit in Oct and then in Nov.

They also prefer to see 1 deposit for simplicity.

Remember it will be office specific and then officer specific what they will allow.

With the money , either banked or income method, 1 mistake and you have to start the process over.

@Barry *******

no your annual date will be basically static.

Being able to apply early allows you to work around your schedules, fix any potential issues, etc.

Some apply on the last day, not a good plan.

@Barry *******

your 12 mths of deposits , must be 12 mths on the day you apply, NOT from the date your visa was initially approved.

So you need the transfers to start asap because you may apply 30 days before the end of your extension.

@Dawn *********

AGAIN the 90 day Non-O is also done at your home country.

You can find it where I posted the screen shot.

@Barry *******

and it must be 12 transcations on the application date not the visa expiry date.

@Barry *******

the smartest and safest path in to leave the 800k in untouched until the new extension is inked under the Income method.

I have seen people fail over a few baht drop in the account because of service fees.
