Since then, there have been "confidential diplomatic dealings" aimed at moving Mohammed Rashed out of the US and fulfilling an earlier commitment to deport him, court filings show.
Rashed was released from federal prison in March 2013 for the bombing of Pan Am 830, which killed a Japanese teenager and injured more than a dozen passengers aboard the Hawaii-bound plane.
He was sentenced to prison in 2006 under a plea deal that allowed for his release last year and required him to cooperate with investigations into other terrorist plots he knew about.
The US government said as part of the agreement that it would work to deport Rashed to a country of his choice after he served his time on murder and conspiracy charges.

Emails and other documents obtained by the AP from US Immigration and Customs Enforcement gave details on why Rashed remains in custody well after his release from prison.
Israel captured the West Bank from Jordan in 1967 and controls access in and out of the territory.
But the Israeli Ministry of Foreign Affairs said in a June 25, 2013, memo that Rashed's Palestinian passport and birth certificate "contain material discrepancies" about his place and date of birth.
The memo to the US Embassy does not specify the discrepancies but said the request would be reconsidered if he submitted better documentation to prove past residence in Palestinian Authority areas.
Even before that rejection, government officials had discussed coordinating travel plans with other foreign countries.
"It will take a little push to have Jordan accept and provide a security detail," one email said.
