You can check from the European Commission's regulated professions database if your profession is regulated in the host country. The database also contains information on the competent authorities.
Recognition of professional qualifications within the EU/EEA
A decision on recognition of professional qualification is needed if practicing the profession requires a certain training or work experience. Those professions are called regulated professions.
EU Professional Qualifications Directive
The EU directive on the recognition of professional qualifications aims to facilitate employment in another EU or EEA country. The directive establishes rules according to which a member state must recognise professional qualifications acquired by an EU or EEA citizen in other another member state. The directive specifies for example what kind of documents the competent authority may require as appendices to an application for recognition of professional qualification.
The Finnish National Agency for Education functions as the national assistance centre for the recognition of professional qualifications. The assistance centre provides information about qualifications and competencies as well as recognition procedures in Finland and other EU and EEA member states.
Internal Market Information Exchange System (IMI)
If you apply for recognition of your professional qualification in another member state, the competent authority that makes the decision may ask for information about your professional qualifications from the Finnish competent authorities through the Internal Market Information Exchange System (IMI).
European Professional Card
