Does Thailand have a citizenship test? How naturalisation works
Last reviewed: October 15, 2026 · Checked against the official source linked on this page.
Under Thailand’s Nationality Act, a foreigner applying for naturalisation must normally have lived in Thailand continuously for at least five years, be of good behaviour, have a regular occupation and have knowledge of the Thai language. Applications are filed with the Special Branch of the Royal Thai Police (or provincial police), and the Minister of Interior has discretion to approve them. Applicants are interviewed in Thai. There is no official written civics test.
This set is a civics practice quiz, not an official exam. It covers Thailand’s system of government, key moments in its history, and its geography, culture and symbols. Always confirm the current rules with the Special Branch Bureau or the Ministry of Interior.
