That's not good. P6C is an old code suggesting a finding under INA Sec. 212(a)(6)(C)(i), "In general. - Any 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." I personally would get assistance from an immigration lawyer.
