To work in Greece as an employed worker, you need:
a national visa for employment;
a residence permit for employment.
According to the new Migration Code, Greece implements a system of volumes of admission of non-EU nationals for the purposes of dependent/salaried employment, which are included in a joint ministerial decision issued every two years setting the maximum number of jobs for salaried employment by region and specialty jobs. For this decision to be issued, the opinions of competent bodies (Economic and Social Council of Greece, Greek Manpower Employment Organisation, the Regions of the country), with regard to the current employment needs in the Greek territory, are taken into consideration. These needs are defined mainly according to the following criteria: consultation between the regional authorities and employer agencies, the interest of national economy, the feasibility of the employment, the labour offer by Greek nationals, citizens of the European Union or legally residing in Greece non-EU nationals per specialty and the percentages of unemployment per section of employment.
On the basis of this maximum number, employers who wish to employ salaried staff should apply to the Decentralized Administration of their place of residence, submitting also i) a valid work contract of at least one year, where it is clearly mentioned that the monthly remuneration of the person to be employed will amount to at least that of an unskilled worker and ii) a tax certificate where it is evidenced that the employer can actually pay this remuneration. The Secretary General of the Decentralized Administration can only approve the employment of non-EU citizens by the specific employee, if the specialization in question is included in the aforementioned joint ministerial decision and the number allowed has not been covered already. This approval is being sent to the consular authority where the employees concerned are informed to present themselves in order to sign the employment contract and receive their visa to enter the country.
