Naturalization is the legal process for making a person a citizen of a country of which he or she was not born or derived citizenship by law. It generally includes fulfilling certain specified conditions of residency, language, and other requirements provided by the country and then having a test on citizenship or an interview. Once naturalized, one enjoys the rights of a citizen: to vote, to work in the country. The process and requirements for naturalization vary from country to country, but common criteria often include having lived in the country for a certain number of years, demonstrating proficiency in the national language, showing good moral character, passing a test on the country's history, government, and laws, and swearing an oath of allegiance. Naturalization entitles the individual to the same rights and privileges enjoyed by native-born citizens, such as obtaining a passport, getting social services, and being able to take part in political life
