Title 18 › PART III — PRISONS AND PRISONERS › CHAPTER 306 — TRANSFER TO OR FROM FOREIGN COUNTRIES › § 4105
When a person serving a prison term in another country is brought into U.S. custody, they stay under the Attorney General and must serve the same time and conditions as if a U.S. court had given the sentence. They get credit for days spent in custody before the sentence began that relate to the crime. Any time-credit the foreign country already gave for good conduct, work, or other reductions counts. After transfer, the person also gets good-behavior credits on the remaining time at the rate in section 3624(b), based on the total sentence certified by the foreign authorities. If the foreign country gave no good-time credit, the 3624(b) rate is used on the certified sentence. Credits can be withheld as allowed in section 3624(b). Any U.S. sentence imposed while the person is serving the foreign term is added together with that foreign sentence as if the foreign sentence were a U.S. sentence.
