"The lawsuit alleges that Facebook refused to hire skilled and affordable workers from the United States for more than 2.6 thousand positions, which Facebook instead reserved for holders of temporary visas," the department noted.

According to the ministry, two years of investigations showed that Facebook deliberately created a hiring system in which "qualified American workers were denied a fair opportunity to learn about vacancies and apply for the position."

Earlier, the US Department of Justice filed a lawsuit against Google, accusing the company of monopoly.
