Citizenship: citizenship by birth: no

note: Israeli law (Law of Return, 5 July 1950) provides for the granting of citizenship to any Jew - defined as a person being born to a Jewish mother or having converted to Judaism while renouncing any other religion - who immigrates to and expresses a desire to settle in Israel on the basis of the Right of aliyah; the 1970 amendment of this act extended the right to family members including the spouse of a Jew, any child or grandchild, and the spouses of children and grandchildren
Definition: This entry provides information related to the acquisition and exercise of citizenship; it includes four subfields:
citizenship by birth describes the acquisition of citizenship based on place of birth, known as Jus soli, regardless of the citizenship of parents.
citizenship by descent only describes the acquisition of citizenship based on the principle of Jus sanguinis, or by descent, where at least one parent is a citizen of the state and being born within the territorial limits of the state is not required. The majority of countries adhere to this practice. In some cases, citizenship is conferred through the father or mother exclusively.
dual citizenship recognized indicates whether a state permits a citizen to simultaneously hold citizenship in another state. Many states do not permit dual citizenship and the voluntary acquisition of citizenship in another country is grounds for revocation of citizenship. Holding dual citizenship makes an individual legally obligated to more than one state and can negate the normal consular protections afforded to citizens outside their original country of citizenship.
residency requirement for naturalization lists the length of time an applicant is required to live in a state before applying for naturalization. In most countries citizenship can be acquired through the legal process of naturalization. The requirements for naturalization vary by state but generally include no criminal record, good health, economic wherewithal, and a period of authorized residency in the state. This time period can vary enormously among states and is often used to make the acquisition of citizenship difficult or impossible.
