One 2012 registration form showed the applicant checked the NO box for citizenship, then wrote in later that they were a legal resident but not yet a citizen. PILF says it still doesnt have all the ones its entitled to. The Public Interest Legal Foundation said it uncovered dozens of examples of people who registered in Harris County, home to Houston, over the past two decades who either admitted they werent citizens or left the box blank, yet were registered anyway.
