Is a Ukrainian citizen who has been to Poland from 2021 with a visa valid until April 22 (now it is being extended) can go to Ukraine and after 2 weeks come back to Poland?

Update: 14.06.2023

The validity of visas issued to citizens of Ukraine has been extended until March 4, 2024.

In the case of leaving Poland, when re-entering a Ukrainian citizen, it is not possible to invoke the residence right resulting from the extension of the visa validity period referred to above. It should be noted that, in accordance with the special legal regulations introduced in connection with the Russian aggression against Ukraine, citizens of Ukraine who came to the territory of the Republic of Poland from Ukraine in connection with the military operations conducted in this country from February 24, 2022, have the opportunity to obtaining the consent of the commanding officer of the Border Guard post to enter Poland and, consequently, receiving a PESEL UKR. Granting permission for entry seems justified, as the Russian military aggression is still ongoing and its effects affect the entire territory of Ukraine.
