Why Partner With Attori Law
Foreign perspective, Thai legal expertise
Foreign-owned ourselves, we understand both how international families actually navigate this process, and how Thai immigration law applies to them.
A coordinated process, not a patchwork of separate applications
We manage the dependent's application alongside the primary visa holder's, rather than treating them as two unrelated cases that happen to be filed around the same time.
We know exactly what documentation Thai authorities actually accept
Translation and notarization standards for foreign certificates vary in practice, not just on paper. We prepare documents to the standard that gets accepted the first time.
Direct access to the people doing the work
You deal with the person managing your case, not a rotating point of contact with no real authority over it.
We explain the reasoning, not just the result
You'll understand why your family qualifies the way it does, and what that means going forward, not just receive a stamped visa and a bill.
A relationship that grows with your family's needs
A dependent visa today, a work permit or school enrollment tomorrow. We handle what comes next, rather than treating each matter as a one-off.

FAQs
Who qualifies for a Non-O dependent visa?
Spouses, children under 20, and in some cases parents. You need proof of the relationship, such as a marriage or birth certificate, translated into Thai and notarised if it was issued abroad. The primary visa holder also has to be meeting the requirements of their own visa.
Which visas can sponsor a dependent?
Non-O holders, including those here on a retirement visa or for family reasons. Non-B work visa holders. Non-ED student visa holders. And long stay categories such as BOI, LTR and Smart Visa. In every case the primary holder needs to be compliant with their own visa for the dependent application to succeed.
How long is the dependent visa valid?
It starts at 90 days, matching the primary holder's visa. It can then be extended to one year at a Thai Immigration Office, provided the documents and financial proof are in order, and renewed annually after that.
Can I switch to a dependent visa from another visa?
Often, yes, and without leaving Thailand. It depends on the visa you hold now, your nationality, and Immigration's decision. We check whether you qualify before starting anything.
What happens if the primary visa holder's visa expires?
The dependent visa is tied to it, so it becomes invalid at the same time. Renewing the primary visa on time is what protects the rest of the family's status. Dependants usually need to supply their documents again at each renewal.
Can a dependent work in Thailand?
No. A dependent visa allows you to live here, not to work. To take a job you would need to move to a work visa and obtain a work permit. Working without both carries penalties for the employee and the employer.
Can I get a dependent visa through my Thai spouse or child?
Yes. Being married to a Thai national or having a Thai child both qualify you. You need proof of the relationship and to meet the financial requirements. If the marriage was registered outside Thailand, the certificate has to be translated and notarised.
