We would like to inform you that about working in Poland, the future employer must apply for a work permit for you. It makes the whole process complicated because you need to find a job before you are allowed to work. This means that you have two options to find a job before coming to Poland:

Coming to Poland without any type of work permit and changing your legal status after finding work. And if you find an employer willing to hire you and that your residence is legal (based on a visa or residence permit). In order to obtain a work permit, your future employer needs to fill out a work permit application that includes the name of the company that hires you and the future job title within this company. This has major implications because your work permit is only valid for the company and position assigned. If you decide to leave your company, you will lose your work permit. Likewise, if you want to get a new job, the new employer must go through the process of applying for a new work permit for you.
