Yes — Thailand’s LTR visa (administered by the Board of Investment, BOI; 10 years, multiple entry, renewable) includes a dependent arrangement, but every word of the rule needs to be read precisely: who counts as a dependent, the cap on how many, and the fact that dependents themselves carry a security requirement. This article breaks the dependent rules down word by word from BOI’s current official page, then lists the fees and process.
Who Counts as a Dependent: The Official List
BOI’s current page recognizes two categories of eligible dependents:
1. Spouse;
2. Children under age 20.
Two precise points, stated as the official wording gives them: a same-sex marriage is recognized as an eligible dependent relationship; a partnership is not eligible — the official wording treats marriage and partnership separately, so check against the actual legal form of your relationship.
The Cap: Up to 4 per Principal Holder
Each LTR holder may bring a maximum of 4 dependents — this is the current official page’s figure. If you want to bring more than 4 dependents, the excess is not covered by the dependent arrangement and must be checked separately against whichever visa route applies to them.
Dependents Have Their Own Security Requirement
Dependents must separately meet one of three security options:
- Health insurance of at least USD 50,000;
- Or Thai social security;
- Or a bank deposit of at least USD 25,000 per dependent, maintained for at least 12 months.
Read this as a separate tier from the principal applicant’s: the principal applicant’s own three options are health insurance of at least USD 50,000, Thai social security, or a bank deposit of at least USD 100,000 maintained for at least 12 months — the deposit threshold differs by person (at least USD 100,000 for the principal applicant, at least USD 25,000 per dependent), so plan finances on a per-person basis.
Fees and Process
Fees: the processing fee for the 10-year, multiple-entry visa issued in Thailand is THB 50,000 per person — the “per person” basis means each dependent is billed separately; a family of four is charged four times over. Issuance outside Thailand (embassies and consulates) costs differently and may be significantly higher, as published by the receiving channel.
Process: the official LTR process has four steps — submit the application and documents through the online system; eligibility review results are notified within 20 working days (this can be extended if further documents are requested); pre-clearance takes 1–3 working days, and after receiving the endorsement letter you must schedule visa collection within 60 days (at an overseas mission, via e-visa, or at the Bangkok One Stop Service Center); a work permit review applies separately where relevant. Details of the document checklist and submission method for dependent applications follow BOI’s current requirements — confirm before submitting.
A Few Misunderstandings
Misunderstanding 1: “Parents can also be LTR dependents.”
The official page’s list of eligible dependents is spouse and children under 20 — parents are not on the list; their own arrangements to come to Thailand must be checked against whichever visa applies to them separately.
Misunderstanding 2: “Paying more lets you bring more than 4.”
A maximum of 4 dependents per holder is the current official page’s figure — anyone beyond that must be checked separately against their own applicable visa route.
Misunderstanding 3: “Dependents don’t need their own security.”
Dependents must separately meet one of three security options — the deposit tier is at least USD 25,000 per dependent, maintained for at least 12 months, calculated separately from the principal applicant’s deposit (at least USD 100,000).
Misunderstanding 4: “Same-sex partners can never be dependents.”
Read the official wording precisely: a same-sex marriage is recognized as an eligible dependent relationship; a partnership is not eligible — check against the legal form of the relationship, with BOI’s determination governing case by case.

A spouse and children under 20, up to a maximum of 4 dependents per holder.

Under the deposit option, at least USD 25,000 per dependent, maintained for at least 12 months (or alternatively health insurance of at least USD 50,000, or Thai social security).
