You're wrong. Katie is right. This is not about illegals who are changing states. This is about illegals who are coming over the southern border from Mexico. Illegal entrants become illegal immigrants when they're not caught by the Border Patrol. They absolutely, positvely DO ad to the number of illegal immigrants in the United States. No amount of fuzzy math or label changing will change that fact.
Pinal County, the county mentioned in the article (did you even read it) is in southern Arizona. It's the most frequently travelled county of illegal immigrants in Arizona. Your comments defy logic.
