INS, 956 F.2d 236 (11th Cir. 1992) (factual admissions could properly be considered by immigration courts in establishing the "reason to believe" ground of inadmissibility where a noncitizen's plea did not result in a conviction under the former Federal Youth Corrections Act: "We conclude that conviction and sentencing under the FYCA ought not actually improve petitioner's immigration status by disallowing the admission of the factual basis merely because of the invocation of the FYCA. (emphasis in original)."); contra, Matter of Seda, 17 I. & N. 550 (BIA 1980)(guilty plea cannot have greater consequences than the ultimate disposition of a case), modified on other grounds Matter of Ozkok, 19 I. & N. Dec. 546 (BIA 1988).
