What residence stages exist for non-EU citizens?

The usual route runs from the type D visa to prolonged residence (up to one year, renewable). After five years of lawful, uninterrupted residence, permanent residence and the EU-wide long-term resident status become available. The Migration Directorate of the Ministry of Interior is in charge; forms and fees are on its official pages. Which residence ground fits your situation is best clarified with Svetlana in advance.
