Losing your job does not automatically mean you are staying illegally. If you are staying in Poland based on a temporary residence and work permit issued due to employment with an employer with whom you no longer work, you should report this information in writing to the Office. You will find the form to do so HERE.
It does not mean that your stay in Poland has become illegal. Still, the loss of work in such a situation provides the grounds for starting the procedure of withdrawing your temporary residence permit. If there was no employer indicated in your decision to grant the residence permit, but you have the right to work in Poland, then your legal situation depends on the permission you have.
On the other hand, if you are staying in Poland having a residence card or a national visa and the period of your regular stay in Poland ends on 16 April 2020, then under regulations introduced on 31 March 2020, your residence in Poland is extended by law until the 30th day following the date of cancellation of an epidemic state/epidemic emergency (the state which was last in force). Your legal stay is extended for this period automatically - it does not require you to submit any additional documents or issue a new residence card. If after the expiry of this period, i.e. 30 days after the cancellation day of the state of the epidemic state/epidemic emergency (the state which was last in force), you wish to continue to stay in Poland, you should apply for a temporary residence permit or, if you have already applied earlier, submit Annex No. 1 to the application, confirming that you will be employed for over 3 months.
