Q1221. What strict linguistic rules govern numerical and proper noun translations at the MFA?
Answered by the NYC Visa & Translation legalization desk
Accuracy and consistency matter more than any assumed universal MFA spelling formula. First, reproduce names using the spelling in the holder’s passport or the relevant official registration record. Match company names to supporting corporate records, and keep that spelling consistent throughout. Preserve numerical values, decimal places, units, document numbers, and dates; when converting Buddhist Era and Gregorian years, check the conversion carefully. Do not silently correct discrepancies in the source document: obtain a corrected original or ask how an explanatory note should be presented. Confirm the required translation language, translator certification, and formatting for your particular submission. A common pitfall is changing name spellings between attachments. Verify current requirements with the Department of Consular Affairs before filing.
