Azeri is another name for Azerbaijani — the official language of the Republic of Azerbaijan and the most widely spoken Turkic language after Turkish. About 30 million people speak it, with the majority actually living in Iran rather than in Azerbaijan itself. For US-bound document translation, the practical question is the script: Azerbaijani written in Azerbaijan uses the Latin alphabet since 1991, while Azerbaijani written in Iran uses Perso-Arabic. We match each project to a translator who handles the source script and is familiar with the relevant civil-document conventions — usually for USCIS asylum, family-court, or commercial paperwork.
