Your visa explained ...

In general, if you (or your host) file a new TM30, you need to file a new TM30 when back but if the address on file hasn't changed, you don't.

But as mentioned before, it depends on the policy of the individual immigration offices around the country.

Or 3'800THB for a Multiple Re-Entry Permit in case you intend to leave Thailand several times during the validity of your Visa or Extension to Stay.

I got 1.25% fixed interest over 5 years which will easily cover any bank charges.

I use the exact same "Fixed Savings Account" from Bangkok Bank since many, many years for my extension of stay and never ever had a problem.

Before you go for your extension, ask the bank for a statement for immigration and they know what you need.

I would suggest to send me $1'000 per month and you and your family can comfortably live on $3'000 per month here in Thailand.

Check-in and Immigration are two different places.

If you're in Thailand with Passport A, you book your flight on that Passport.

Then in Malaysia you use Passport B to go through Immigration.

In Malaysia you book your flight with Passport B, clear immigration on that one and once you're in the plane you change back to Passport A.

Now be aware, should you have been banned in one of the countries, it doesn't matter with which Passport you travelled, they will know, it's on file.

If Malaysia accepts dual nationality or not is not really a concern for you but for Malaysian citizens.

You only can swap passport if you fly. If you cross by land it's not possible as customs wants to see your exit stamp from Thailand or vice versa.

You can only leave a country on the same passport you entered it (or replacement documents if you lost or they were stolen whilst in the country)

Over all it doesn't bring much to swap passports whilst traveling as your details are feed in to the system including fingerprints and iris scanns.

Don't count on getting a "7 day Order To Leave" stamp. If that's not granted, you have to leave within 24 hours.
