Citizens of the Republic of Moldova with a biometric passport can work officially in the countries of the European Union; they can officially take up employment in the EU countries on the basis of the short-stay visa also. This is only possible for seasonal work that does not exceed 90 days.
The liberalization of visas for the citizens of the Republic of Moldova is stipulated by EU Regulation NO. 259/2014 of the European Parliament and of the Council from April 3, 2014.
Thus, as of 28 April 2014, citizens of the Republic of Moldova who hold biometric passports may travel visa-free in 26 Schengen countries, except for Great Britain and Ireland. According to this Regulation, the visa-free travel to the EU states does NOT give the right to work.
In order to work, live or study in the EU, the citizens of the Republic of Moldova have to obtain a long-stay visa - Type D visa (issued for a period of more than 90 days and issued for the purpose of: study, entrepreneurship, employment in the workplace, family reunification, etc.)
