INA §212(a)(6)(C)(i)，an “alien who, by fraud or willfully misrepresenting a material fact, seeks to procure (or has sought to procure or has procured) a visa, other documentation, or admission into the United States or other benefit provided under this Act is inadmissible.”什么意思？简单说，就是任何外国人通过欺诈或故意歪曲主要事实以便企图获得、已企图获得、或已获得美国的签证、其它入境文书、或移民法规定的其它好处或移民福利，那么这个外国人将不许入境。Inadmissible就是不能拿绿卡的意思。
