A former FBI informant once suspected of being a Chinese double agent has agreed to plead guilty to lying to federal agents and to a tax charge, U.S. law enforcement officials said Friday.

Katrina Leung, a wealthy socialite from San Marino, Calif., was expected to enter a plea Friday in U.S. District Court in Los Angeles. She would serve no jail time under an agreement reached with federal prosecutors, one official told The Associated Press in Washington, D.C.

The officials spoke on condition of anonymity.

Leung's lawyers, Janet Levine and John Vandevelde, confirmed there was an agreement but declined to specify the terms.

"There is an agreement that will resolve the case, that will finally and forever dismiss all charges that question her loyalty to this country and will settle all tax matters," the attorneys said in a statement.

They added, "She looks forward to resuming her life and putting this horrible nightmare behind her."

In January, U.S. District Judge Florence Marie Cooper dismissed all charges against Leung, rebuking federal prosecutors for deliberate misconduct in the case. However, the government was considering appealing Cooper's action.

Leung's lover, FBI agent James J. Smith, pleaded guilty to making false statements last year. Prosecutors in that case say Leung took classified documents from Smith's briefcase.
