I stopped studying, but I still have a valid residence card - can I stay in Poland?

It is your duty to inform the governor about the end of your studies and the permit will be withdrawn. Remember that if you do not do this, the university where you studied will inform us. After receiving the information, the permit will be withdrawn and the card will be invalidated. If you want to stay in Poland and your visa is no longer valid, submit a new application for a temporary stay consistent with the purpose of your stay before your permit is withdrawn. If you do not do this, you will be able to stay in Poland for another 30 days after receiving the decision to withdraw your residence permit.
