According to the immigration law in force, third-country citizens who are beneficiaries for Golden visa as property owners can be accompanied by their family members, who will be granted the permanent residence permit too. As family members are considered: spouses; the other spouse or partner with whom a third-country national has a cohabitation agreement in Greece; the direct unmarried descendants of the spouses, who are under the age of 21; the direct unmarried descendants of the investor or of the other spouse/partner, provided that their custody has been legally entrusted to the sponsor (for his/her children) and to the other partner (for his/her children), under 21 years of age, and the adopted children under the legal process as well; the direct relatives of the spouses in the ascending line. These family members are issued a resident permit of the same duration as the applicant, but this permit does not include access to employment. The children of the applicant, who have been originally admitted to the country under the terms and requirements of resident permit for property owners, are issued with a resident permit for family reunification until the age of 21. After that, it is possible to acquire a renewal as an independent residence permit until they reach the age of 24 and then it is possible to renew it further according to pertinent immigration legislation.
