Marriage Visa, short for Non Immigrant O visa based on being married with Thai National, gives you 90 days of stay.

Marriage Visa, short for 1 year Extension of Stay based on being a family member of a Thai National to extend the 90 day period.

Different things with different names changed in an easy name makes the confusion,

@Kieran ******

why would it not possible to enter at a border crossing?

There is a list of reasons why a person can be denied, first regulation is not having a valid passport.

If you have a valid passport it might help

@Michael ********

yes, I can.

It is actually the whole page who explains that you can NOT make appointments based on the fact that the Thai Embassy in Malaysia is now using the on-line application website from the Thai Ministry Of Foreign Affairs, the link is several times mentioned, BUT special for you:



So no walk to the Embassy, no need for appointments, no need to make hard copies to hand over, just visit the website while being in Malaysia and apply by sending in files and information.

You can NOT change from one visa to the DTV inside Thailand.

IF your visa is used you can leave the country before the Admitted until date and apply for a new DTV abroad.

OR if you are on an Extension of Stay permitted up to xx/xx/xx, than depending on reason of issue, you cancel this Extension of Stay, leave Thailand and apply for the DTV.

It was not hard to find that answer:

Talk to your employer, the Ministry of Labor does not hold your passport, your employer does.

No, You Single Entry Non Immigrant B is used on entry and gave you 90 days of stay, when this ends you can only extend this based on being employed.

Alternative to hope for the best is to apply for the correct visa for your visits.

You go with both passports to the local Immigration Office to transfer some stamps

If you travel, use both passports

If you like to apply at Immigration for a new 1 year Extension of Stay.

The requirement actually is:

at least 2 months prior application a minimum of 800,000 Thb into a Thai bank account on your name, the money MUST stay in that account for at least 3 months after approval of the extension and the rest of the year NOT less than 400.000 Thb.

And this comes back year after year as you apply each year for a new 1 year stay
