A foreigner entered Poland after 14 March 2020, from Ukraine i.e. on 9 May 2020, holding a work visa, which was valid until 21 May 2020. Until when is he able to stay legally in Poland and when should he apply for a residence card?

If you entered Poland after 14 March 2020 and you have not applied for a temporary residence permit before the expiry of the visa validity period, i.e. during the period of your legal stay, you will still be able to submit an application for a temporary residence permit. In accordance with the special legal regulations introduced on 31 March 2020 and 18 April 2020, the deadline for submitting an application for a temporary residence permit has been extended until the 30th day following the date of cancellation of the epidemic emergency or epidemic state (the last state that was in force). Your stay, from the expiry date of the visa, will be considered legal, but on the condition that you apply for a temporary residence permit until the 30th day following the date of cancellation of the epidemic emergency or epidemic state (the last state that was in force).
