Umar Farouk Abdulmutallab, 25, who attempted to detonate an underwear bomb aboard a Detroit-bound American aircraft on Christmas Day in 2009, will be sentenced on Thursday.
His sentencing, which was earlier slated for last month, is coming up almost 26 months after he was arrested.
If convicted of all counts, Abdulmutallab faces a possible life sentence; and would be moved from the federal prison in Milan to federal super-maximum prison in Florence, Colorado, where other convicted terrorists are kept.
Abdulmutallab had, last October, pleaded guilty to the charges, which included the attempted use of a weapon of mass destruction and attempted murder of 289 people.
In an application, his lawyer, Anthony Chambers, argued that a mandatory life sentence for the Nigerian would be unfair for a crime that didn't hurt any passenger on that flight.
Abdulmutallab admitted working for al-Qaeda on that botched mission, and praised two of its main figures, Osama bin Laden and Anwar al-Awlaki, both of whom were killed by US Navy Seals and a drone attack respectively.
