Q1128. How to process visa health screening certificate translations for foreign applicants?

Answered by the NYC Visa & Translation certified translation team

Health screening certificates for Thai visa and work-permit purposes follow the specific category's medical requirements, and the translation rules depend on where the screening was done. The Thai-side rule: for work permits and most long-stay extensions processed in Thailand, the medical certificate is issued by a Thai hospital or clinic on the standard form (in Thai, accepted directly — no translation needed), covering the prescribed conditions. The foreign-screened cases: for visa applications at Thai embassies abroad (some categories require medical certificates at application), the foreign medical certificate is translated into Thai or English per the embassy's instruction and legalised where required; and for specific categories with health requirements (some LTR and long-stay categories), the insurance and health evidence follows the category's checklist. Points that matter: the medical certificate has a short validity (commonly 1–3 months for visa purposes) — the examination, translation, and submission must be sequenced within the window; the certificate must cover the conditions the category prescribes — a general health letter that omits a required test is rejected; and the examining facility's credentials matter — some authorities specify approved or recognised facilities. For the reverse direction (Thai medical certificates for foreign visa applications — common for Thai nationals emigrating), the Thai certificate is translated into the destination language and certified, with the destination country's panel-physician rules checked first: many countries (US, UK, Australia, Canada, New Zealand) require examination by their own panel physicians, and a non-panel certificate is not accepted regardless of translation. Confirm the specific visa category's medical requirements and accepted facilities before the examination is booked.
