How long can a Romanian work permit last?

Permanent residence. Romanian work visa can be used for permanent residence with grey card. There are two types of permanent residence in Romania, one is a five-year card and the other is a 10-year card. 10 card can only be obtained if you marry a Romanian, and the others are five years. Almost forever. Just renew your residence card at the immigration office every five years. The procedure is very simple.
