Can my spouse and children be included on the LTR Visa?

Each dependant applies for their own LTR Dependant Visa, which is a derivative visa category. It is not independently qualifying. The dependant’s eligibility flows entirely from the primary applicant, which means the primary applicant must reach full pre-approval before the dependant can be approved.

In the most common scenario, the primary applicant and the dependants submit their applications at the same time, but the primary applicant’s file always tracks slightly ahead and must successfully complete both Stage 1 (Qualifications Endorsement) and Stage 2 (Medical Coverage) before the dependant can be approved. The primary applicant does not need to have the visa physically stamped in their passport yet, but those two stages must be fully complete.

For spouse applicants, the core document required is a marriage certificate, but there is meaningful nuance here. The BOI expects the marriage to be evidenced as current within the past six months. Since most married couples have been together far longer than that, the straightforward fix is to obtain an updated copy or extract of the marriage certificate from the relevant civil registry or government office. If that is not possible, the next best approach is to provide the original marriage certificate alongside a jointly filed tax return showing both names within a recent period. If neither of those works, Thailand Blueprint can work with you on legalization of the original certificate through the Thai Embassy system as a fallback option.

For child dependants, the required documentation varies depending on whether the child is a biological child (birth certificate), adopted child (birth certificate, adoption certificate, and court order), or stepchild (birth certificate, court order of adoption, and marriage certificate linking the child’s biological parent to the primary applicant). Each dependant is subject to the same government issuance fee as the primary applicant.
