Omani citizenship renunciation requires careful coordination between a foreign nationality application and Oman’s approval process. Applicants generally need official proof that the foreign application was submitted, property and outstanding-obligation certificates, and Ministry of Interior approval before completing foreign acquisition. Omani identity documents must then be surrendered through the prescribed route, generally within 90 days of nationality loss. This guide explains the legal sequence, documentary requirements, fee discrepancy, overseas surrender rules, translation decisions and common filing risks under Oman’s 2025 nationality law and 2026 executive regulation.
