How long does it take to transition from a Non-O visa to a Marriage visa in Thailand?

The “90-days Non-Imm-O Family Visa” is your visa. You will get stamped in for a 90-days stay permit. The visa expires upon entry.

In Thailand you will apply on Immigration for a “1-year extension of the stay permit based on marriage”.

Having entered on a Non-Imm visa type will help to get a Thai bank account opened.

For the account opening, the minimum requirements are a “certificate of residence” from Immigration that is specially issued for the purpose to get a bank account opened.

Further, you will need a Thai SIM card registered on your name and your passport number.

You can apply for the “1-year extension of stay permit” up from the last 30 days of your 90-days stay permit.

On the day you apply, the deposit of a minimum of 400,000 THB must have been in sitting in your bank account for a minimum of 2 months, and this must be confirmed by the “bank letter of guarantee” (in Thai: rab roong thanakan)

The application fee is 1900 THB.

You initially will get issued the 1-year extension for 4 weeks “under consideration”. Within this period, Immigration is going to conduct a home visit. After this period, you can pick up the 1-year-extension stamp . . . . . . . I suggest you leave the 400,000 THB sitting in your account until you got issued the 1-year extension of stay stamp. After this, you can use the money for living expenses. However, two months before the date of the next annual extension of stay permit application, the 400,000 THB minimum need to be back in the account

Were you married in Thailand because, if not, there are a few steps you should do before travelling to enable you to get your foreign marriage registered in Thailand which you will need for your extension?

If married in the UK :

then register your marriage at your local Amphur

The Non-O is your marriage visa and you apply for a 12 month Extension of Stay (based on marriage) when you have seasoned your 400k for two calendar months and with no more than 45 or 30 days (depends on the Immigration OIffice you use) remaining on your entry stamp.

The 90 day Non-O is your visa, you will next apply for an extension of stay based on marriage. It will help you open a bank account but you might also need a residence certificate from immigration and a Thai SIM registered against your passport. You can apply for an extension of stay when you are down to the last 30 days of your entry stamp from the Non-O AND your 400k baht has been in bank account for 2 calendar months date to date
