To apply for dual citizenship while studying abroad, first verify if your home country and study country permit dual nationality. Research specific eligibility criteria, such as residency duration or marriage requirements. Gather necessary documents, including passports, birth certificates, and proof of residency. Submit an application to the immigration authorities of your study country, often requiring fees and interviews. Consult both countries’ embassies for precise procedures, as laws vary. Maintain legal status in your study country throughout the process. Ensure compliance with tax and legal obligations in both nations post-approval.
