Citizenship provides you with all the rights normally afforded to any citizen of a respective country such as the right to vote, succession of citizenship to minor children, free settlement, the right to welfare, education, and social security. It means you may live and work (and be employed); your children can access the education system of the country.
For example, with a Malta passport, you can travel visa-free to more than 180 countries. EU citizenship is extremely well protected, expensive and unfortunately does not meet everybody’s budget.
Alternative good cost options still apply for an application for a global passport in countries such as Turkey and Vanuatu however obtaining residency in various jurisdictions including Europe is always an option.
