For expats, a second passport from your new country can be really useful and open up more opportunities. In some countries it’s really easy to gain dual citizenship, in others it’s more complicated and in some it is impossible. Dual citizenship is when a person is recognised as a citizen in two countries. Having dual citizenship can provide an expat with extra security: easier access to investment opportunities; more employment options; voting rights; sometimes extra tax benefits. Unfortunately, not all countries allow dual citizenship. In some cases, the country you are living in may not accept dual citizenship. In other cases, it may be your home country that prevents you from holding dual citizenship. For a full list of where dual citizenship is and is not allowed, click here.
