Second citizenship, often referred to as dual citizenship, allows an individual to be a citizen of two countries simultaneously. This status grants various benefits, including the freedom to travel, work, and live in either country, access to social services, and potentially more advantageous tax arrangements. It also offers a level of security and flexibility, as individuals can leverage the resources and protections of both nations. Acquiring second citizenship can be achieved through different means such as investment, marriage, ancestry, or naturalization.
