In the course of the proceedings, I completed my studies and obtained a diploma from a Polish university - I still want to stay in Poland, what should I do?

If you want to work in Poland, but you haven't found a job yet, you can retrain job search application. If you already have a job, you can retrain application for residence and work. A graduate of full-time studies at a Polish university does not need a work permit, you have free access to the Polish labor market.
