Jonathan Pollard, the spy who was released from U.S. prison on Friday after three decades, will work as an analyst at an investment firm in New York, according to documents submitted by his legal team to a federal court in New York.

Pollard, who was sentenced to life in prison for spying against the United States on Israel’s behalf, was released on parole.

According to a report in The New York Times, the documents were presented as part of a petition brought forth by Pollard's lawyers seeking to cancel some of the restrictions placed on him as part of the parole terms.

According to Pollard's lawyers, he will be required to wear an electronic bracelet so his movements can be monitored at all times. Also, his computers and those of any employer who hires him will be subjected to "unfettered monitoring and inspection."

Pollard's lawyers argue his employment as an investigative analyst at an investment firm might complicate the electronic monitoring.

In a statement announcing their legal challenge, the lawyers called the conditions "onerous and oppressive."

"There is no basis whatsoever to treat Mr. Pollard in that manner, and doing so is vindictive and cruel, as well as unlawful," lawyers Eliot Lauer and Jacques Semmelman said.

Pollard has said he wants to immigrate to Israel where his second wife, Esther, lives, and where he can expect to receive substantial Israeli government back-pay. He was granted Israeli citizenship while in prison.

But a U.S. official said Friday that Pollard would have to stay in the United States. "Obviously the one thing at issue is the requirement that he remains in the United States," Deputy National Security Adviser Ben Rhodes was quoted as saying.

"Once again, the president does not have any plans to alter the terms of his parole."
