Lithuanian nationality law
Introduction
 

**Lithuanian nationality law** operates on the jus sanguinus principle, whereby persons who have a claim to Lithuanian ancestry, either through parents, grandparents, great\-grandparents may claim Lithuanian nationality. Citizenship may also be granted by [naturalization](/wiki/Naturalization "Naturalization"). Naturalization requires a residency period, an examination in the [Lithuanian language](/wiki/Lithuanian_language "Lithuanian language"), examination results demonstrating familiarity with the [Lithuanian Constitution](/wiki/Lithuanian_Constitution "Lithuanian Constitution"), a demonstrated means of support, and an [oath](/wiki/Oath "Oath") of loyalty. A [right of return](/wiki/Right_of_return "Right of return") clause was included in the 1991 constitution for persons who left [Lithuania](/wiki/Lithuania "Lithuania") after the [Soviet occupation](/wiki/Occupation_of_the_Baltic_states "Occupation of the Baltic states") in 1940 and their descendants. Lithuanian citizens are also [citizens of the European Union](/wiki/Citizenship_of_the_European_Union "Citizenship of the European Union") and thus enjoy [rights of free movement](/wiki/Freedom_of_movement_for_workers%23Transitional_provisions_in_new_member_states "Freedom of movement for workers#Transitional provisions in new member states") and [have the right to vote](/wiki/Lithuania_%28European_Parliament_constituency%29 "Lithuania (European Parliament constituency)") in elections for the [European Parliament](/wiki/European_Parliament "European Parliament").
