The law strengthening the use of the Ukrainian language adopted by Kyiv proves that Ukraine is following the Lithuanian, Latvian and Estonian scenarios, which means that disloyal parts of the population are excluded from public life based on their languages. The next step will be issuing passports for foreigners, as in the Baltic countries.
Alien's (non-citizen's) passports are issued in Estonia and Latvia. They were granted to the people who did not reside in the countries before their annexation by the Soviet Union in 1940, as well as to their descendants, in case they did not successfully pass exams proving proficiency in the state languages and knowledge of the countries' history.
Despite the new law's ambiguity (president-elect Volodymyr Zelensky already stated he will be reviewing it), it is ungrounded to speculate about the introduction of alien's (non-citizen's) passports in Ukraine.
