Russia is allegedly sending thousands of migrants and foreign students to fight in the war against Ukraine for visa renewal.

According to Bloomberg, the assessment was done by some European officials who alleged that the Kremlin is using foreign students as extra manpower using the tactics first deployed by the Wagner mercenary group. 

The report added that Russia has been threatening not to extend the visas of African students and young workers unless they agree to join the military, according to officials familiar with the matter.

Moscow has also been enlisting convicts from its prisons while some Africans in Russia on work visas have been detained and forced to decide between deportation or fighting, one European official said. 

Some of those people had been able to bribe officials to stay in the country and still avoid military service, said the official, who spoke on the condition of anonymity.

According to reports citing Ukrainian intelligence, Russia has engaged in a global recruitment drive to enlist foreign mercenaries in at least 21 countries, including several nations in Africa. 

Army recruitment campaigns offer lucrative signing bonuses and salaries for those who’ll join up as contract soldiers. 

Recruiters have also targeted migrants and students who previously looked for employment in Russia, and in some cases have lured others over with promises of lucrative work before forcing them to train and deploy to the front.
