People who are against giving undocumented workers temporary work visas would say that they actually do nothing to contribute to the U.S. It has been argued that undocumented workers take away from jobs that legal citizens could do. Undocumented workers have been shown to take jobs away from other groups such as poor African Americans or poor Hispanic Americans. The undocumented workers compete with these groups for the jobs. From different studies, it has been shown that on average an illegal immigrant household costs Federal State and local taxpayers $4,867 per year. This is unfair to taxpayers to have their money go towards illegal immigrants. It has also been shown that many hospitals in California have been forced to close because illegal immigrants have come in for treatment when they have no form of health insurance and do not plan on paying the medical expenses. It can be said that the burden of illegal immigrants outweighs their contributions to the workforce and U.S. society. Illegal immigrants can also receive “free” services from the government, which is actually funded by citizen’s tax money. People who are con giving undocumented workers try to show that illegal immigrants’ costs outweigh their benefits.
