illegal immigration
Illegal immigration has risen as a top issue of concern among the American electorate over the last 20 years as the levels of both legal and illegal immigration into America have reached historical proportions!
About half of America’s illegal immigrants cross national borders without the required authorization, visas, criminal background checks, medical exams, or terrorism checks which are designed to protect Americans and legal immigrants. The other half are visa overstays where people violate their pledge to leave America when their visas expire!
There are many problems with illegal immigration ranging from violent crime, drug trafficking, contagious diseases, lost jobs, and taxpayer resources, and this issue has proven to be one of the most contentious in America.
