How do the companies prove that they didn't find anybody better (from Poland or EU)?
The companies won't do the research. They submit a notification of a vacancy in the District Labour Office and then the registries analysis is made about unemployed and job seekers. If it happens that there's enough people that meet the requirements resulting from the submitted offer, then a recruitment is being organized among people who are looking for the job. The Starost shall take a decision in a timely manner. Information is passed to an employer who then submit it as an attachment to the application for a work permit.
