Destination Guide
Thailand, one category at a time.
Thai permanent residence runs through five named categories under a strict annual national quota. This page sets out what genuinely applies for Thailand, rather than implying an open-ended points system.
Application categories for Thailand
Each category below links to the full guide for Thailand. Where Thailand's own system has named, distinct programs — rather than one general category — we break that out underneath.
Visitor Visa
Full Visitor Visa guide →Many nationalities can visit Thailand visa-free for short stays under the visa exemption scheme; others require a Tourist Visa (TR) arranged in advance through an embassy or consulate.
Business Visitor
Full Business Visitor guide →Short-term business visitors to Thailand generally use a Non-Immigrant B visa — the business, non-work-permit version — sponsored by the inviting Thai company, for activities such as meetings or negotiations that don't involve local employment.
Study Visa
Full Study Visa guide →Studying in Thailand generally requires a Non-Immigrant visa in the 'ED' (education) category, sponsored by an accredited Thai educational institution, with an extension of stay arranged after arrival.
Work Visa
Full Work Visa guide →Working legally in Thailand typically requires both a Non-Immigrant B visa and a separate work permit issued by the Ministry of Labour, sponsored by a Thailand-registered employer.
Digital Nomad
Full Digital Nomad guide →The Destination Thailand Visa (DTV) is a multi-entry visa for remote workers and freelancers whose income comes from outside Thailand. It allows an initial stay per entry with a single extension available in-country, and the visa itself remains valid for an extended period, letting holders re-enter repeatedly without reapplying.
Permanent Residence
Full Permanent Residence guide →Thailand grants permanent residency through the Immigration Bureau under an annual quota system, generally requiring at least three consecutive years on a Non-Immigrant visa, with categories for employment, investment, business, and family (including marriage to a Thai national).
Thailand's Permanent Residence is granted under five specific categories, each with its own financial or relationship threshold, and the total number of approvals per nationality is capped by an annual national quota — meeting a category's requirements doesn't guarantee a place within that year's quota.
Investment
For applicants who have made a qualifying minimum investment in Thailand, held for the required period.
- Applicants able to document a qualifying Thailand-based investment meeting the current minimum
Business / Working
For applicants in an executive role at a Thai-registered company meeting a minimum capital and income threshold, or for long-term work-permit holders meeting a minimum income or tax-paid threshold over several consecutive years.
- Executives or long-term work-permit holders meeting the current income and tenure requirements
Family
For the spouse, parent, or dependent child of a Thai national or existing Thai permanent resident.
- Spouses, parents, or dependent children of a Thai national or Thai permanent resident
Expert
For applicants with recognized specialized skills or academic qualifications, certified by the relevant Thai government authority, and a qualifying period working in that specialized field in Thailand.
- Applicants with specialist qualifications certified by a Thai government authority
Family Sponsorship
Full Family Sponsorship guide →Foreign nationals who are the spouse, parent, or dependent of a Thai citizen — or, in some cases, of a foreign resident — may be eligible for a Non-Immigrant O (family) visa, generally followed by an annual extension of stay.
Parent & Grandparent Visa
Full Parent & Grandparent Visa guide →Thailand does not have a separate long-stay visa category specifically for parents or grandparents of foreign residents. Depending on the family relationship, a Non-Immigrant O (family) visa or the standard visitor visa may apply. See our Visitor Visa service for the general process.
Refusals
Full Refusals guide →Thai visa refusals from an embassy, consulate, or the Immigration Bureau are not always accompanied by detailed written reasons — we help organize the available documentation and information before you reapply.
Thai Citizenship
Thai naturalization is discretionary and slow — most applicants need to hold Thai Permanent Residence first, then meet a further multi-year requirement before the Ministry of Interior will even consider the application, which can itself take years to decide.
- Generally hold Thai Permanent Residence first, or qualify through marriage to a Thai citizen with several years of continuous residence
- Meet Thai language and points-based eligibility criteria covering factors such as age, income, education, and years of residence
- Pass character and background checks, with final approval resting at the discretion of the Minister of Interior
Thai nationality law and naturalization criteria are set by the Ministry of Interior and involve substantial discretion; approval is never guaranteed and timelines can run into years. Covalyn Migration does not guarantee approval — confirm current requirements with the relevant Thai authority directly.
