Route to permanent residence

Thailand's Board of Investment (BOI, the government agency that jointly administers the scheme with the Immigration Bureau) publishes the SMART Visa programme, launched 1 February 2018 to attract skilled foreign personnel and investors into 13 targeted 'S-Curve' industries (including digital, biotechnology, automation and robotics, aviation and logistics, and 'Human Resource Development in Science and Technology'). It has 5 categories: SMART 'T' (Talents / highly-skilled experts), 'I' (Investors), 'E' (Senior executives), 'S' (Startup entrepreneurs) and 'O' (spouse and legitimate children of a SMART Visa holder). The Talents category, the one most directly reachable by a science/technology graduate, requires average income of not less than 100,000 baht/month (or equivalent) for a general business role, or not less than 50,000 baht/month for someone contracted by a startup or a retired expert — while an expert working at a government institution, an educational institution, or in alternative dispute resolution has no minimum income requirement at all. A SMART Visa holder is granted permission to stay in Thailand for up to 4 years, needs to report only once a year (versus the usual 90-day reporting for other visa types), and may re-enter the Kingdom an unlimited number of times; a spouse and legitimate children receive matching residence rights. A foreign national already in Thailand on another visa type may switch to a SMART Visa if they meet the published criteria, and applications are processed through the BOI's own online SMART Visa system.

Route to citizenship

Thai citizenship by naturalisation (แปลงสัญชาติเป็นไทย) for an ordinary foreign national is governed by Section 10 of the Nationality Act B.E. 2508 (1965) and its amendments, and administered by the Department of Provincial Administration (DOPA), Ministry of Interior, whose own 'Nationality Act Clinic' publishes the applicable criteria directly: having reached the age of majority; holding a certificate of residence or alien registration certificate with a name entered in the civil registration; continuous domicile in Thailand for not less than 5 years, counted from the date the certificate of residence or alien registration was obtained; an honest occupation, evidenced by an occupation certificate from the Office of Foreign Workers Administration or a provincial employment office, meeting an income threshold that itself depends on the applicant's connection to Thailand — not less than 80,000 baht/month if the applicant has no connection to Thailand, dropping to not less than 40,000 baht/month if the applicant has a connection such as being married to a Thai national, having a Thai national child, or having graduated with a higher-education degree from an educational institution in Thailand; evidence of having paid tax for not less than 3 years; a salary/income certificate; basic knowledge of the Thai language (able to speak and understand spoken Thai); and good conduct, verified through a criminal background check (fingerprints submitted for checking), plus checks on political activity, drug involvement, and national-security-related conduct with the relevant agencies. StudyPath found no DOPA page addressing dual nationality or an original-nationality-renunciation requirement for this Section 10 route, so no claim is made on that point.
