How long is the Greece employment residence permit valid and when do I renew?

An employment residence permit in Greece is typically issued for an initial period of two years, provided your work contract supports it. On renewal it can be extended for a longer period, commonly up to three years.

You should apply to renew roughly two months before the permit expires. Filing late, even within a short grace window, can attract an administrative fine, and letting the permit lapse can jeopardize your legal status, so plan renewals early.
