The three- and ten-year bars to admissibility of section 212(a)(9)(B)(i) of the Immigration and Nationality Act (the Act) and the permanent bar to admissibility of section 212(a)(9)(C)(i)(I) of the Act were added by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (Div. C of Pub. L. 104-208 (September 30, 1996) (IIRIRA)). The amendments enacting sections 212(a)(9)(B) and (C) became effective on April 1, 1997. To date, DHS has not implemented regulations describing how unlawful presence accrues for the purposes of 212(a)(9)(B)(i) and (C)(i)(I). DHS intends to propose regulations to this effect, which may include or expand upon certain current agency policies, including whether certain failures to abide by the conditions of admission as a nonimmigrant can result in accrual of unlawful presence. Further, DHS intends to address how aliens subject to inadmissibility under 212(a)(9)(B)(i) and (C)(i)(I) may be admitted to the United States after remaining outside the United States for the required period of time.
