Former Green Bay Packers linebacker Andy Mulumba can come back to the United States now that he has signed with the Kansas City Chiefs.

His agent, Tom Tafelski, confirmed to ESPN.com on Friday that Mulumba has signed a one-year deal that included a small signing bonus. Mulumba, a native of the Congo and a Canadian citizen, had to leave the U.S. after the Packers decided not to tender him as a restricted free agent last month, Tafelski said.

Mulumba spent his first three NFL seasons with the Packers, who signed him as an undrafted free agent from Eastern Michigan.

“Andy would like that thank the Packers for what they did to help his NFL career,” Tafelski said in a text message. “They are truly a classy organization, and it was a great few years.”

Tafelski said now that Mulumba is employed again, the Chiefs will work with immigration authorities to help him work toward his goal of attaining U.S. citizenship. Mulumba also visited the Patriots before signing with Kansas City.

Mulumba played 22 games for the Packers over three seasons, including six last season mostly on special teams. He recorded 36 career tackles and one sack. He made a full recovery from a 2014 knee injury that ended his season after just two games.
