Naturalization is the legal act or process by which a non-citizen in 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 obeying and upholding that country's laws, taking and subscribing to the oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture. To counter multiple citizenship, most countries require that applicants for naturalization renounce any other citizenship that they currently hold, but whether this renunciation actually causes loss of original citizenship, as seen by the host country and by the original country, will depend on the laws of the countries involved.
Jus sanguinis is a principle of nationality law by which citizenship is not determined by place of birth but by having one or both parents who are citizens of the state. Children at birth may automatically be citizens if their parents have state citizenship or national identities of ethnic, cultural, or other origins. Citizenship can also apply to children whose parents belong to a diaspora and were not themselves citizens of the state conferring citizenship. This principle contrasts with jus soli.
Canadian nationality law is promulgated by the Citizenship Act since 1977. The Act determines who is, or is eligible to be, a citizen of Canada. The Act replaced the previous Canadian Citizenship Act in 1977 and has gone through four significant amendments, in 2007, 2009, 2015 and 2017.
The conferment of a person, as a citizen of India, is governed by Articles 5 to 11 of the Constitution of India.

The United States nationality law is a uniform rule of naturalization of the United States set out in the Immigration and Nationality Act of 1952, enacted under the power of Article I, section 8, clause 4 of the United States Constitution, which reads: Congress shall have Power - "To establish a uniform Rule of Naturalization..." The 1952 Act sets forth the legal requirements for the acquisition of, and divestiture from, American nationality. The requirements have become more explicit since the ratification of the Fourteenth Amendment to the Constitution, with the most recent changes to the law having been made by Congress in 2001.
Italian nationality law is the law of Italy governing the acquisition, transmission and loss of Italian citizenship. Like many continental European countries it is largely based on jus sanguinis. It also incorporates many elements that are seen as favourable to the Italian diaspora. The Italian Parliament's 1992 update of Italian nationality law is Law no. 91, and came into force on 15 August 1992. Presidential decrees and ministerial directives, including several issued by the Ministry of the Interior, instruct the civil service how to apply Italy's citizenship-related laws.
South Korean nationality law defines who is a South Korean citizen, as well as the procedures by which one may be naturalized into South Korean citizenship or renounce it.
The original United States Naturalization Law of March 26, 1790 provided the first rules to be followed by the United States in the granting of national citizenship. This law limited naturalization to immigrants who were free White persons of good character. It thus excluded Native Americans, indentured servants, slaves, free blacks and later Asians, although free blacks were allowed citizenship at the state level in certain states. It also provided for citizenship for the children of U.S. citizens born abroad, stating that such children "shall be considered as natural born citizens," the only US statute ever to use the term. It specified that the right of citizenship did "not descend to persons whose fathers have never been resident in the United States."
Afroyim v. Rusk, 387 U.S. 253 (1967), is a major United States Supreme Court case in which the Court ruled that citizens of the United States may not be deprived of their citizenship involuntarily. The U.S. government had attempted to revoke the citizenship of Beys Afroyim, a man born in Poland, because he had cast a vote in an Israeli election after becoming a naturalized U.S. citizen. The Supreme Court decided that Afroyim's right to retain his citizenship was guaranteed by the Citizenship Clause of the Fourteenth Amendment to the Constitution. In so doing, the Court struck down a federal law mandating loss of U.S. citizenship for voting in a foreign election—thereby overruling one of its own precedents, Perez v. Brownell (1958), in which it had upheld loss of citizenship under similar circumstances less than a decade earlier.
Status as a natural-born citizen of the United States is one of the eligibility requirements established in the United States Constitution for holding the office of President or Vice President. This requirement was intended to protect the nation from foreign influence.

Israeli citizenship law regulates who are and can become citizens of Israel.
Vance v. Terrazas, 444 U.S. 252 (1980), was a United States Supreme Court decision that established that a United States citizen cannot have his or her citizenship taken away unless he or she has acted with an intent to give up that citizenship. The Supreme Court overturned portions of an act of Congress which had listed various actions and had said that the performance of any of these actions could be taken as conclusive, irrebuttable proof of intent to give up U.S. citizenship. However, the Court ruled that a person's intent to give up citizenship could be established through a standard of preponderance of evidence — rejecting an argument that intent to relinquish citizenship could only be found on the basis of clear, convincing and unequivocal evidence.
Nguyen v. INS, 533 U.S. 53 (2001), was a United States Supreme Court case in which the Court upheld the validity of laws relating to U.S. citizenship at birth for children born outside the United States, out of wedlock, to an American parent. The Court declined to overturn a more restrictive citizenship requirement applying to a foreign-born child of an American father and a non-American mother who was not married to the father, as opposed to a child born to an American mother under similar circumstances.
Citizenship of Russia is regulated by the federal act regarding citizenship of the Russian Federation, Constitution of the Russian Federation, and the international treaties that cover citizenship questions to which the Russian Federation is a party.

Nishikawa v. Dulles, 356 U.S. 129 (1958), is a United States Supreme Court case in which the Court ruled that a dual US/Japanese citizen who had served in the Japanese military during World War II could not be held to have lost his US citizenship unless the United States could prove that he had acted voluntarily.
Rogers v. Bellei, 401 U.S. 815 (1971), was a decision by the United States Supreme Court, which held that an individual who received an automatic congressional grant of citizenship at birth, but who was born outside the United States, may lose his citizenship for failure to fulfill any reasonable residence requirements which the United States Congress may impose as a condition subsequent to that citizenship.
The Nationality Act of 1940 revised numerous provisions of law relating to American citizenship and naturalization. It was enacted by the 76th Congress of the United States and signed into law on October 14, 1940, a year after World War II had begun in Europe, but before the U.S. entered the war.
