NaturalizationNaturalization (or naturalisation) is the legal act or process by which a non-citizen of a country may acquire citizenship or nationality of that country. It may be done automatically by a statute, i.e., without any effort on the part of the individual, or it may involve an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture.
Jus soliJus soli (dʒʌs_ˈsoʊlaɪ , juːs_ˈsoʊli ), commonly referred to as birthright citizenship, is the right to acquire nationality or citizenship by being born within the territory of a state. Jus soli was part of the English common law, in contrast to jus sanguinis, which derives from the Roman law that influenced the civil-law systems of mainland Europe.
