Israeli nationality law defines the criteria under which a person can be granted citizenship of Israel. It also deals with the Right of Return for Jewish diaspora. In general, Israel's nationality follows jus sanguinis as the primary mechanism through which a person may obtain citizenship, rather than jus soli. A citizen of the modern state of Israel is called an Israeli. Apart from citizenship, there is another civil status which can be held by residents of Israel: the permanent residency status. It is most common among Syrian citizens of the Golan Heights and among East Jerusalem residents, but it occurs also among other non-citizens.
