By definition in Latvian law, non-citizens are not stateless. While they have rights akin to citizens, for example, the right to reside in Latvia without visas or temporary residence permits, rights in other areas are curtailed. Non-citizens cannot vote, although they can participate to a lesser degree in public policy through NGOs. Pension rights are limited, and non-citizens cannot hold certain positions in local and national government, the civil service, and other governmental entities. Non-citizens are exempt from military service, which was compulsory for male Latvian citizens until 2006. UN Committee on the Elimination of Racial Discrimination described non-citizens' position as discriminatory in 1999.
