Russian President Vladimir Putin Monday signed a decree allowing all Ukrainian citizens to apply for Russian citizenship through a simplified procedure. Ukrainians only need to provide proof of Ukrainian residency and citizenship, along with divorce and name-change documents, in order to apply. Parents applying on behalf of their children are also required to provide their child’s birth certificate.

Putin’s order expands on a 2019 decree that afforded the residents of the largely-unrecognized Donetsk and Luhansk People’s Republics to apply for Russian citizenship, a move that critics have called “passportization.” The term “passportization” refers to a Russian foreign policy tactic where Russia naturalizes citizens foreign states en masse in order to undermine the national sovereignty of another country.

Previously, Ukrainians could only apply through an expedited process if they lived in Russian-occupied Ukrainian territory. In May, Putin signed a decree that gave residents of the Russian-occupied Kherson and Zaporizhzhia regions access to the same simplified naturalization procedure previously afforded to residents of Donetsk and Luhansk.

Putin’s decree comes days after Russia’s State Duma passed legislation to direct the Russian economy to support the Russian war effort in Ukraine. It also represents a move to assert Russian dominance over Ukraine after the EU voted to give Ukraine “candidate status” for admission in response to Russia’s invasion.
