Can my husband extend his visa and switch to a Non-O visa after our marriage in Thailand?

Young Nationality doesn’t change anything here. If a foreigner is legally married to a Thai woman, he applies for a Thai marriage visa/extension—same rules whether he’s Belgian, American, or anything else.

People sometimes call it a “family visa,” but it’s still based on the marriage, not the husband’s nationality. 👍

Graham Seal I've read it, but the question was where best after the wedding you can get a non o marriage

Nancy Van Rysselberghe You didn’t mention your husband’s nationality, which actually matters a lot here because visa rules and options can vary depending on the country. It makes it harder for people to give precise advice.

That said, in general:

Yes, he can usually extend his visa exemption once for 30 days at immigration (before it expires on April 17).

After that, switching to a Non-O visa (based on marriage) inside Thailand is possible, but there are a few important conditions:

• You must already be legally married (not just in process)

• You need all required documents ready (marriage certificate, financial proof, etc.)

• Immigration typically requires that he still has valid stay remaining when applying

If the marriage isn’t finalized in time, he likely won’t be able to convert directly and may need to leave Thailand and apply for a Non-O visa from a Thai embassy abroad.

So timing is key here—if the marriage happens before his extension ends, you’re in a good position. If not, plan for a visa run.

Nancy Van Rysselberghe ok so he can defenitly get a extension , its best to go a week before his exemt expires. You can put the reason for request , require more time to apply for the correct visa.

Nancy Van Rysselberghe Can I convert a Tourist Visa to a Marriage Visa in Thailand?

Yes. You can enter Thailand on a tourist visa and, after your marriage, apply to change your visa status to a Non-Immigrant O visa based on marriage, subject to immigration requirements.

If you later meet the requirements for a longer stay, you may then apply for a one-year extension of stay based on marriage at your local immigration office.

Do I need a Non-Immigrant O visa before I can marry a Thai national?

No. You do not need a Non-Immigrant O visa to get married in Thailand. You can enter Thailand on a tourist visa or visa exemption, register the marriage, and afterwards apply for a Non-Immigrant O visa based on marriage.

What is the typical process after marrying a Thai national?

Many applicants follow this general sequence:

Enter Thailand (tourist visa or visa exemption).

Register the marriage in Thailand.

Apply at Thai Immigration to obtain Non-Immigrant O status based on marriage (where available).

Open a Thai bank account (requirements vary by bank/branch).

Deposit 400,000 THB (for the marriage extension).

Apply for the one-year extension of stay based on marriage.

Do I need 400,000 THB in the bank before applying for a marriage visa?

No. The 400,000 THB financial requirement applies to the one-year extension of stay based on marriage, not to the initial visa application. In practice, many people open the account after they have Non-Immigrant O (marriage) status.

Can I apply for a Non-Immigrant O visa outside Thailand?

Sometimes, yes. Thai embassies/consulates abroad may issue a Non-Immigrant O visa, but requirements vary significantly by location and can change. Approval may also depend on the reviewing officials.

Can a support letter from my Thai spouse help with a Non-O visa application?

Sometimes. If you apply for a Non-Immigrant O outside Thailand (including before the marriage), a short support letter from your Thai spouse (or future spouse) can sometimes help in addition to other supporting evidence (for example, spouse ID/house registration copies, proof of relationship, travel/accommodation details, and proof of funds such as bank statements).

Important: There is no guarantee this will be accepted. Requirements and decisions can vary by embassy/consulate, location, and the reviewing officials.

This is from Thai law online, my power has gone out so had to do a phone google and it matches with the basic requirements but photos required can vary between 2 and 10 or more depending on the office used. It would be nice if it was the same everywhere but it is Thailand.

Jason Bracegirdle it is not best to leave it until your last week to get your extension unless you use Jomtien Immigration where this is a requirement

Jason Bracegirdle. Its handle about immigration office. I fix my 90 days,after 32 days. But i must wayt,for stamp in passport. My turist-visa going ut 29 mars. What day i must go to immigration and they stamp my 90 days.

I know,its not work everywhere. Only go and speak with theme,and they told you the rules.

@Nancy ******************

he cannot do it without leaving because he doesn't have a Thai bank account. No Thai bank account, no non-O visa. He must be able to show 400,000 in his Thai bank account to apply for a non-O visa in Thailand.

His ONLY option is to leave Thailand and apply for a non-O visa from a Thai embassy after you're married. He can show funds from any bank account for the embassy. Then when he returns he can use that non-O visa to open a bank account and deposit the funds required for the extension.
