Foreigners, who are dissatisfied with the decision of the Voivode, may appeal against it to the Head of the Office for Foreigners (UdsC) in Warsaw, through the proper Voivode who issued the decision. Written appeal should be lodged within 14 days from the date of receipt of the decision.
The foreigner may appeal against the decision of the Head of the Office for Foreigners in the administrative court within 30 days from the date of receipt of the decision.
Lodging the appeal at the administrative court does not constitute a legalisation of the stay. This means that unless the foreigner has another valid document authorizing them to stay in Poland, they should leave Poland in such case. You may be in danger of deportation then!
