How does the DTV Dependant sub-category work for spouses and children?

Spouse and child dependants apply through the same Embassy or Consulate as the primary applicant in most cases, with their own documentation package. The primary and dependant applications may be submitted at the same time, but the primary applicant’s file tracks slightly ahead of the dependants, and some Royal Thai Embassies and Consulates will require proof that the primary applicant has already been approved before processing the dependant applications. Thailand Blueprint generally recommends obtaining the primary DTV approval first before submitting dependant applications, to reduce complications during processing. This mirrors the sequencing logic used in the LTR Dependant Visa category, though the DTV version is procedurally simpler.

For spouse applicants, the central qualifying document is a marriage certificate demonstrating the legal marital relationship to the primary DTV holder. The “current within 6 months” issue applies here as it does for the LTR Dependant Visa, and is addressed in its own right further below.

For child dependants under 20, the required documents depend on whether the child is a biological child, adopted child, or stepchild. Biological children need a copy of the birth certificate, a copy of the parents’ marriage certificate (or notarized court order in cases of sole custody), and copies of both parents’ or legal guardians’ identification. In some jurisdictions (the United States in particular), a notarized consent letter permitting the minor to travel abroad, signed by both parents, is also required if the minor is traveling alone. Adopted children need a copy of the birth certificate, the adoption certificate, the court order of adoption, and copies of the legal guardian(s)’ identification. Stepchildren need a copy of the birth certificate, the marriage certificate between the child’s biological parent and the primary DTV applicant, and in cases where the primary applicant has formally adopted the stepchild, a court order of adoption.

All dependant documents must be in Thai or English. Translated documents must be notarized.

There is no strict published limit on the number of dependants that may be included under a single primary DTV holder, but the financial threshold scales with each additional dependant under the Sponsorship Method.
