Under the INA, the term "sentence" explicitly refers to any form of punishment that must be served inside a prison. Any "street time" (i.e., period of probation, parole, or supervised release) that was imposed as part of the defendant's sentence plainly does not count as term of imprisonment. A sentence of imprisonment with parole is called a "bifurcated sentence," and various U.S. courts of appeals have held that this is not a suspended sentence. House arrest is also not imprisonment for INA purposes.
