KYIV, Ukraine - He and his parents were among the last in their village to take a Russian passport, but the pressure was becoming unbearable.

By his third beating at the hands of the Russian soldiers occupying Ukraine’s Kherson region, Vyacheslav Ryabkov caved. The soldiers broke two of his ribs, but his face was not bruised for his unsmiling passport photo, taken in September 2023.

It wasn’t enough.

In December, they caught the welder on his way home from work. Then one slammed his rifle butt down on Ryabkov’s face, smashing the bridge of his nose.

“Why don’t you fight for us? You already have a Russian passport,” they demanded. The beating continued as the 42-year-old fell unconscious.

“Let’s finish this off,” one soldier said. A friend ran for Ryabok’s mother.

Russia has successfully imposed its passports on nearly the entire population of occupied Ukraine by making it impossible to survive without them, coercing hundreds of thousands of people into citizenship ahead of elections Vladimir Putin has made certain he will win, an Associated Press investigation has found. But accepting a passport means that men living in occupied territory can be drafted to fight against the same Ukrainian army that is trying to free them.

A Russian passport is needed to prove property ownership and keep access to health care and retirement income. Refusal can result in losing custody of children, jail - or worse. A new Russian law stipulates that anyone in the occupied territories who does not have a Russian passport by July 1 is subject to imprisonment as a “foreign citizen.”

But Russia also offers incentives: a stipend to leave the occupied territory and move to Russia, humanitarian aid, pensions for retirees, and money for parents of newborns - with Russian birth certificates.

Every passport and birth certificate issued makes it harder for Ukraine to reclaim its lost land and children, and each new citizen allows Russia to claim a right - however falsely - to defend its own people against a hostile neighbor.

The AP investigation found that the Russian government has seized at least 1,785 homes and businesses in the Donetsk and Zaporizhzhia regions alone. Ukraine’s Crimean leadership in exile reported on Feb. 25 that of 694 soldiers reported dead in recent fighting for Russia, 525 were likely Ukrainian citizens who had taken Russian passports since the annexation.

AP spoke about the system to impose Russian citizenship in occupied territories to more than a dozen people from the regions, along with the activists helping them to escape and government officials trying to cope with what has become a bureaucratic and psychological nightmare for many.

Ukraine’s human rights ombudsman, Dmytro Lubinets, said “almost 100% … of the whole population who still live on temporary occupied territories of Ukraine” now have Russian passports.

Under international law dating to 1907, it is forbidden to force people “to swear allegiance to the hostile Power.” But when Ukrainians apply for a Russian passport, they must submit biometric data and cellphone information and swear an oath of loyalty.

“People in occupied territories, these are the first soldiers to fight against Ukraine,” said Kateryna Rashevska, a lawyer who helped Ukraine bring a war crimes case against Putin before the International Criminal Court. “For them, it’s logical not to waste Russian people, just to use Ukrainians.”
