US prosecutors alleged Facebook "channeled" jobs to visa holders by avoiding advertising on its careers website, accepting only physically mailed applications for some posts, or refusing to consider US workers at all.
The December 2020 lawsuit represented a new front in the mounting judicial and anti-trust regulatory pressure on the social media giant, which reaches billions of people globally on its platforms.
"Facebook is not above the law, and must comply with our nation's federal civil rights (protections)," Assistant Attorney General Kristen Clarke said in a statement.
Facebook did not immediately reply to a request seeking comment on the agreement.
Under the Department of Justice settlement, Facebook will pay $4.75 million to the United States, and up to $9.5 million to eligible people impacted by the company's alleged discrimination.
The leading social network is also required to train its employees on the anti-discrimination measures in US immigration law and do more to recruit US workers.
The lawsuit targeted more than 2,600 positions with an average salary of some $156,000, offered from January 2018 to September 2019.
Prosecutors alleged the internet giant reserved positions for candidates with H1-B "skilled worker" visas or other temporary work visas.
Skilled-worker visas are precious to Silicon Valley tech firms hungry for engineers and other highly-trained talent, with Asia home to many keenly sought workers.
The settlement comes as Facebook faced a storm of criticism since a whistleblower leaked internal studies showing the company knew its sites could be harmful to young people's mental health.
US authorities have struggled to regulate social media platforms like Facebook amid criticism that the tech giants trample on privacy and provide a megaphone for dangerous misinformation.
