my wife was denied visa by the US Embassy,reason is 212(a)(6) (6)(c)(ii). It's over 3 years now

A denial under §212 (a) (6) (C) (ii) is for misrepresenting oneself as a US citizen. If the misrepresentation occurred on or after September 30, 1996, the individual is forever barred from the United States. If committed before that time, a waiver of misrepresentation can be applied for based on extreme hardship to a US citizen or permanent resident spouse or parent. If your wife believes that the finding was defective, she can make another application and attempt to convince the consular officer that she did not make such a misrepresentation.
