Relocating Your Whole Family to Thailand: A Complete Legal Guide to the LTR Visa for Families in 2026
— FAMILY RELOCATION · JUNE 2026
Moving to Thailand as an individual is one thing. Relocating with a spouse and children — across multiple document jurisdictions, with different legal requirements for each family member — is an entirely different legal undertaking. This guide explains exactly how the LTR Visa supports family relocation, and what you need to know before beginning the process.
BY WARUS AND JAMES RAYDAR INTER LAW Family Relocation
The decision to relocate a family internationally is rarely straightforward. Beyond the personal and logistical dimensions of a major move, there are legal requirements, document obligations, immigration timelines, and compliance conditions that must all be carefully managed — and managed correctly — if the relocation is to proceed smoothly and on schedule.
Thailand's Long-Term Resident (LTR) Visa is, in our view, the most compelling immigration pathway currently available for internationally mobile families who meet the financial thresholds. No other Thai long-stay visa provides a 10-year multi-entry permission, covering a spouse and up to four children, with annual instead of quarterly reporting, meaningful tax advantages, and airport fast-track privileges — all under a single principal application.
This article is written for families: those with a qualifying principal applicant who are planning to bring a spouse, children, or other eligible dependants to Thailand and want to understand the legal landscape thoroughly before engaging counsel and committing to a timeline.
Who Can Be Included as a Dependant on the LTR Visa?
The LTR Visa programme allows the principal applicant — the person who qualifies on the basis of income, assets, or professional credentials — to include qualifying dependants under their application. Dependants receive the same 10-year LTR Visa, the same annual reporting privilege, the same airport fast-track benefit, and in most categories, the same eligibility to apply for a Digital Work Permit independently.
Eligible dependants under the current LTR programme rules include:
A legally married spouse. Thailand's Marriage Equality Act came into force in January 2025, and the BOI has confirmed that same-sex spouses are fully eligible as LTR dependants provided the marriage is legally registered in the country of origin and supported by appropriate documentation.
Children of the principal applicant who are under 20 years of age at the time of application. This covers biological children, legally adopted children, and children for whom the applicant holds legal guardianship, subject to documentation. Adult children aged 20 or above are not eligible under the standard dependant category.
A maximum of four dependants per principal applicant may be included under the standard LTR programme rules currently in force. Expanded dependent eligibility — including parents of the principal applicant — was announced in the BOI's February 2025 update, but implementing regulations from the Ministry of Interior and Immigration Bureau had not been issued as of the date of this article. Families expecting to include parents should seek updated legal advice at the time of their application.
“The LTR Visa is the only Thai long-stay instrument that allows a principal applicant to bring an entire family — spouse and children — under one 10-year application, with no separate income requirements for dependants”
Do Dependants Need Their Own Financial Qualifications?
This is one of the most frequently asked questions from family clients, and the answer is reassuring: dependants do not need to independently satisfy the LTR income or asset thresholds. The qualification rests entirely with the principal applicant. If the principal qualifies — whether on the USD 80,000 passive income route or the USD 40,000 income plus USD 250,000 Thai investment route — the dependants qualify with them.
There is, however, one financial requirement that applies individually to each dependant: health insurance. Every family member included in the LTR application — including each child — must hold a qualifying health insurance policy providing minimum coverage of USD 50,000, inclusive of hospitalisation and medical treatment in Thailand, with at least 10 months of coverage remaining at the date of application.
For families with children who have pre-existing health conditions that complicate insurance applications, an alternative route exists: maintaining a bank deposit of at least USD 25,000 per dependant (USD 100,000 for the principal applicant) for a minimum of 12 consecutive months prior to application. This financial safety net route satisfies the health coverage requirement without requiring an active insurance policy.
The Document Challenge — Why Family Applications Are More Complex
A single-applicant LTR Visa is a manageable process for an organised individual with straightforward income documentation. A family of four, however, introduces multiple layers of complexity that are frequently underestimated by those who begin the process without specialist legal guidance.
Multi-Jurisdictional Documents
Dependant applications require documents that, by their nature, originate in countries other than Thailand. A marriage certificate issued in the United States, children's birth certificates issued in different US states, a criminal clearance from the FBI, and supporting identity documents for each family member — all of these must be authenticated for use in Thailand through the Apostille process.
Under the Hague Apostille Convention (to which both the US and Thailand are signatories), documents issued in the United States can be authenticated by the relevant Secretary of State's office for the state in which the document was issued, or through the US Department of State for federal documents such as FBI criminal clearance. Each Apostille must be obtained separately, and processing times vary by state and document type — typically 2–6 weeks for state-level documents and 4–8 weeks for FBI clearance through standard channels.
Documents not originally in English — including any documents from a country of prior residence — must be accompanied by a certified professional translation into English or Thai before submission to the BOI. For families with recent residence in non-English-speaking countries, this is an additional preparation step that must be factored into the Phase 1 timeline.
Separate BOI Portal Accounts for Each Applicant
A detail that catches many families by surprise: each LTR applicant — including each dependant — must have their own account on the BOI's LTR Visa application portal. Documents for each family member must be uploaded to their individual account, and the dependant accounts must then be correctly linked to the principal applicant's file before submission.
Managing four separate portal accounts simultaneously — with individual document sets, individual status tracking, and coordinated submission — requires a structured approach. Errors in linking dependant accounts are a common source of delay in family applications and, in some cases, lead to Requests for Information (RFI) from the BOI that extend the processing timeline.
Coordinated Insurance Documentation
Each family member's health insurance policy must be individually verified and uploaded as part of their separate application. Where different family members hold different policies — or where a single group policy covers multiple family members — the documentation must be structured to clearly evidence the USD 50,000 minimum coverage for each individual. Group policy documents that do not individually specify per-person coverage amounts are a recurring issue in family applications and must be confirmed in writing with the insurer before submission.
The Application Timeline for Families — What to Expect
A well-managed family LTR application follows a structured phased timeline. Based on our experience with family instructions, the typical end-to-end process from initial engagement to visa stamp collection takes approximately 4–6 months when document preparation begins promptly and no significant issues arise.
Recommended Phased Timeline — Family of 4
Phase 1 (Months 1–3): Eligibility assessment, income and asset structuring, document collection, Apostille processing for all family members, health insurance procurement and policy verification, BOI portal account creation for all applicants.
Phase 2 (Month 3–4): Submission of completed application to BOI for Qualification Endorsement. BOI standard processing is approximately 20 working days, though complex family applications or those requiring clarification may extend to 30–45 working days.
Phase 3 (Month 4–5): Receipt of Qualification Endorsement. The endorsed applicants must collect the physical visa stamp within 60 days of endorsement. Appointment is booked at TIESC in Bangkok or a designated Royal Thai Embassy.
Phase 4 (Month 5–6): Physical visa stamp collection for all family members at a single coordinated appointment. All dependants must collect at the same location as the principal applicant.
What Rights Do Dependants Receive?
LTR Dependant Visa holders enjoy a substantial package of rights and benefits — far exceeding what is available under any other Thai dependant visa category. They receive a 10-year multiple-entry visa with the same initial 5-year stay permission as the principal applicant. They benefit from the same annual reporting obligation (rather than 90-day reporting) and the same airport fast-track privilege at designated international airports in Thailand.
Critically, dependant spouses and children of LTR holders in the Wealthy Global Citizen, Wealthy Pensioner, and Work-from-Thailand Professional categories are eligible to apply for a Digital Work Permit independently. This means a spouse who holds their own professional skills or who wishes to work remotely while in Thailand can do so legally under a Digital Work Permit linked to their LTR Dependant status — without being subject to the standard 4:1 Thai-to-foreigner employment ratio.
Common Mistakes Families Make — And How to Avoid Them
Starting document preparation too late. The Apostille process for FBI criminal clearance typically takes 4–8 weeks through standard channels. Families who begin this process at the same time as the BOI application often face timeline pressure that could have been avoided. We advise beginning document preparation at least 12–16 weeks before the intended submission date.
Assuming one insurer or policy covers the whole family adequately. Many international health insurance policies provide group coverage with aggregate limits rather than per-person minimums. The BOI requires evidence of USD 50,000 coverage per individual — and a group policy that does not individually specify per-person coverage may not satisfy this requirement without a supplementary letter from the insurer. Always confirm per-person coverage amounts in writing before submission.
Relying on an agent platform for a complex family instruction. Automated visa platforms are built for individual, straightforward applications. A family instruction with multi-jurisdictional documents, multiple dependant portal accounts, coordinated insurance verification, and a fixed relocation deadline requires the kind of responsive, expert case management that only a qualified legal practitioner can provide. The cost difference between an agent platform and specialist legal counsel is modest relative to the risk of errors, delays, or — in the worst case — a rejection that sets the family's relocation timeline back by months.
Not accounting for the 60-day endorsement collection window. Once the BOI issues the Qualification Endorsement, all applicants — principal and dependants — must collect their physical visa stamps within 60 days. Families who have not arranged their travel to Bangkok or their embassy appointment in advance can find themselves under significant time pressure. Planning the collection appointment before the endorsement is received is strongly advisable.
