The Kaweah Indian Nation, Inc., is a civic group interested in cultivating a Native American identity. The group is named after the Cahuilla people (which is also pronounced "kah-WEE-yah") and has applied for status as a federally recognized tribe in the USA in the 1980s, a petition which was denied.
Recently, scam artists have sold purported citizenships in the non-recognized tribe, particularly to Mexican nationals who have entered the US illegally. Member of one US tribe, the Kickapoo Tribe of Texas, hold dual citizenship with the USA and Mexico due to historical reasons.
