Dependent visas for spouse and children for individuals

How this case runs end to end

Obtain the embassy affirmation or the required home-country document, legalise it at the Ministry of Foreign Affairs with a certified translation, register at the district office, then use the certified Thai certificate for the dependent visa, school admission or birth registration that follows.

Stage-by-stage timeline

What to prepare

• Passport with every page that carries a stamp, plus the current departure card where one was issued
• Proof of address: registered lease, TM.30 receipt or a house registration extract
• Home-country civil documents already legalised and translated where a Thai office will receive them
• The deadline that governs the filing: permitted stay end date, 90-day due date or renewal date
• Financial evidence in the form the receiving office accepts, such as a bank letter or credit advice
• Insurance documents where the visa category attaches a coverage condition
• One contact person able to confirm instructions and collect documents on the appointment day

What "Dependent visas for spouse and children for individuals" actually involves

This question sits within family, marriage, children and schooling for foreign residents. The authority or standard that governs it directly is the Department of Provincial Administration, the Ministry of Foreign Affairs and the Ministry of Education, and every case is assessed against the rules in force on the day of submission. IVC prepares the file, checks internal consistency and coordinates with the receiving office; we are not a government body and we never guarantee how an authority will decide.

Birth registration in Thailand is made at the district office where the birth occurred, within the statutory period.

International schools generally require legalised transfer certificates and transcripts, and some require the Ministry of Education equivalence process.

Documents issued abroad may have validity windows imposed by the receiving office, counted from the date of issue rather than the date of use.

Rules and requirements to settle before you start

Name spelling must be consistent across the passport, the embassy document and the Thai certificate; a single variation creates work at every later step.

A Thai marriage certificate is often re-legalised and translated again for use in the foreign spouse's country.

Dependent visas are tied to the principal's status, so the dependent's permitted stay follows the principal's extension dates.

Foreign civil documents such as birth certificates, marriage certificates and police clearance are normally legalised in the issuing country first and translated and certified in Thailand afterwards; the order cannot be reversed.

The TM.30 accommodation notification is the duty of the house master or landlord, but the consequences of a gap fall on the resident at the next extension.

The mistakes that cost the most time

The most expensive pattern in expat filings is treating each office as independent. Immigration, the district office, the Land Office and the transport office all read the same underlying documents, and an inconsistency in a name, a date or an address that one office tolerates will stop the file at the next one — usually after the deadline that mattered has already passed.

The second is discovering a reporting duty only when applying for something else. The TM.30 record and the 90-day history are reviewed at extension time, and gaps accumulated months earlier cannot be corrected retrospectively; keeping the record current costs minutes, while repairing it costs an application cycle.

Why files are delayed or returned

• The embassy affirmation was not legalised before it reached the district office
• Names on the passport and the supporting certificate do not match
• The dependent application does not show the principal's current permission to stay
• A required document has passed the validity window the receiving office applies
• The TM.30 record is incomplete or does not match the address on the application
• Translations do not match the original in names, dates or document numbers
