Tips for a Successful Expatriation to Greece

Mastering the Language: A Major Asset

Although English is widely spoken in major cities and tourist areas, learning Greek will help you integrate more easily and fully enjoy your expatriation experience. Many language schools offer intensive courses for adults and children.

Adapting to the Mediterranean Pace of Life

Greece is known for its more relaxed pace of life compared to Northern European countries. Expect different working hours, often with extended lunch breaks and later-ending days. Embrace this “siga siga” (slowly, slowly) culture to fully enjoy the Greek quality of life.

Navigating Bureaucracy

Administrative procedures in Greece can sometimes be complex and time-consuming. Don’t hesitate to seek help from professionals (lawyers, accountants) for your paperwork, particularly for obtaining your residence permit and enrolling your children in school.

Building a Social Network

Join expatriate groups on social media and participate in community events to meet other international families. These contacts will be valuable for exchanging advice and feeling less isolated in your new life.

Enjoying the Cultural Richness

Greece is full of historical and cultural treasures. Take advantage of your stay to explore the country, visit archaeological sites, discover the islands, and immerse yourself in local culture. It’s a unique enrichment opportunity for the whole family.

Relocating to Greece with school-age children represents a stimulating challenge, but also a tremendous opportunity for global exposure. The country’s international schools offer a quality educational environment combining academic excellence with a multicultural approach. Although the cost of these institutions is significant, it’s an investment in your children’s future, opening doors to the best international universities.

Greece, with its rich cultural heritage, pleasant climate, and Mediterranean lifestyle, offers an exceptional living environment for expatriate families. By carefully planning your budget and preparing for the specifics of local life, you can make the most of this unique experience.
