On October 25, 2019, the Attorney General published Matter of Thomas & Thompson holding that adjudicators could only recognize a sentence modification for immigration purposes where the sentence was vacated due to procedural or substantive defect as defined in Matter of Pickering. It was not clear whether this holding was retroactive. Under new DOJ regulations it is now clear that Matter of Thomas & Thompson is not retroactive. Adjudicators will recognize a sentence modification as vacating the sentence for immigration purposes where: (1) the person filed for the sentence modification on or before October 25, 2019; (2) the person relied on the availability to seek a sentence modification where the conviction date was on or before October 25, 2019; (3) there was a clerical or typographical error in the sentence regardless of the date of entry of the sentence; or (4) where the sentence was vacated due to a procedural or substantive defect in the sentencing - regardless of when the sentence modification was filed.
