Double citizenship holders are entitled to several benefits provided by each country you are holding a passport to. Such features may grant the opportunity to use two social insurance systems, a right to vote and be elected in both countries, as well as grants access to public healthcare and education. A person holding two passports is permitted to work and do business in any of two countries not requiring any kind of residence permission or employment visa. Having two passports provides you the opportunity to travel visa-free to a bigger number of countries, depending on which passport you present at the border.

Another advantage of holding two passports is the ability to legally buy and own real estate in both countries. This may be relevant as some governments restrict owning land and/or real estate to nationals of third countries.
