For naturalisation, applicants must be adults, hold an eligible residence document, demonstrate lawful and permanent residence, integration, compliance with tax and social-security obligations, and no public-order or security impediments. The general residence requirement is seven years, while three years applies to EU citizens, spouses of Greek citizens with a child, and certain other categories; the standard fee is €550.
According to the source, Greek naturalisation requires more than a long stay: applicants must demonstrate genuine integration through income, tax compliance, social ties and evidence that Greece is the permanent base of their daily life. The standard route requires seven years of lawful residence, while certain categories may qualify after three years; holders of other eligible documents may face a twelve-year requirement. In practice, applicants should preserve tax-clearance records, employment and social-security evidence, and proof of banking activity. This is particularly relevant to long-term residents, investors, EU citizens and people with family ties to Greece, and should be considered before choosing a residence route.
