Fernandez-Vargas v. Gonzales, 548 U.S. 30 (2006), is a United States Supreme Court case that considered Humberto Fernandez-Vargas, a Mexican citizen who, after being deported, illegally reentered the United States in 1982, and remained undetected for over 20 years, fathering a son in 1989 and marrying the boy’s mother, a U.S. citizen, in 2001. He filed an application to adjust his status to that of a lawful permanent resident, but the Government began proceedings to reinstate his 1981 deportation order under §241(a)(5), and deported him.
