Federal Judge Stephen Robinson said Tuesday that Kerik can remain free, pending his sentencing in February.
Kerik left the federal courthouse in White Plains with his lawyers. He made no comment.
The judge imposed some conditions, including home confinement and wearing an electronic monitoring device.
Kerik was hailed as a hero after the Sept. 11 attack. He avoided as many as three federal trials when he admitted Thursday that he lied about his associations while being considered for the top post at Homeland Security.
