How long can the patient stay, what happens if treatment continues longer, and what official extension or follow-up mechanism exists?
The Embassy states that a single-entry O visa is valid for 90 days from the date of issuance and a multiple-entry visa for one year, while the Ministry's national page states three months for both with one year additionally possible for multiple entry; the two official statements are not reconciled. The Ministry adds that a Non-Immigrant holder is initially granted a stay in the Kingdom not exceeding 90 days unless the Office of Immigration Bureau instructs otherwise. If treatment runs longer, the mechanism is the general one rather than a medical one: those qualified may obtain an additional one-year stay permit counting from the date of entry, applied for at the Office of Immigration Bureau and granted at the discretion of the immigration officer, and anyone wanting more than 90 days must file at a Thai consular mission abroad or at the Office of Immigration Bureau in Bangkok. No treatment-specific extension is described.
