The Non-Immigrant O visa covers family-based stays in Thailand: spouses, parents and children of Thai nationals, and some related situations. Stays are extended yearly at immigration if you still meet the relationship and financial conditions.
Family-based visas depend on documents that prove a relationship and, in most cases, a financial condition. Those documents have to be current, consistent and in the right form, and the wording on each one matters.
We check your marriage or family documents before submission, prepare translations and legalisations where needed and then look after your yearly renewal, re-entry permits and 90-day reports.
This is for you if
- You are married to a Thai citizen and want to live in Thailand.
- You are a parent of a Thai child or a child of a Thai parent.
- You want a team that tracks renewals and reporting.
- You need a re-entry permit so travel does not cancel your stay.
This may not fit if
- You are an unmarried partner of a Thai citizen. Other routes may fit better; ask us.
- You want to work. You also need a work permit and may need a different visa.

Marriage visa and extension of stay
A stay based on marriage to a Thai national is usually extended in yearly steps at an immigration office. The extension needs proof of the marriage, proof of financial means in one of the accepted forms and documents about your address. We prepare the complete file and tell you which financial option is realistic for you. Read more in our guide on the marriage visa with a Thai spouse.
Parents and children of Thai nationals
Parents and children of Thai citizens can have their own family-based route. The documents focus on the family relationship, such as birth certificates and household records. We check them early so you do not discover a problem at the counter.
Re-entry permits
If you leave Thailand during an extended stay without a re-entry permit, the stay normally ends when you cross the border. We arrange re-entry permits so your travel does not cost you your status.
Documents for a family-based stay
Typical documents; the exact list depends on your situation:
- Passport and current visa or stay stamp
- Marriage certificate or family registration documents
- Spouse or family member ID and household records
- Proof of financial means in the accepted form
- Photos and completed forms
- Translations or legalisations where requested
- Proof of address in Thailand
