In 2006 approximately 18 per cent of the total population (420,000 inhabitants of Latvia, slightly less than half of ethnically non-Latvian population) had no Latvian citizenship. Most of them have Latvian non-Citizen Passports, which give them a status similar to permanent residency in other countries. They can reside in Latvia indefinitely and obtain most of the public services ("e.g.", education and healthcare) according to the same conditions as the citizens of Latvia. Non-citizens of Latvia cannot vote during municipal and state elections and are not allowed to work in government, the police and civil services. Several foreign nations also treat citizens and non-citizens of Latvia differently, admitting citizens of Latvia without a visa but requiring visas from non-citizens. Russia used to have an opposite practice, requiring visas from both citizens and non-citizens of Latvia, but allowing non-citizens to travel to Russia with a cheaper visa.
