While immigration has played an important role in US history, the level and size of immigration population have varied considerably. Even though many foreign born nationals migrate to United States for various reasons, the main apprehension is about illegal immigrants who come to US most often from countries with less developed health care systems and more prevalent health problems. While unauthorized immigrants have contributed to the economic growth of the communities, the social change and pressures on public services and are also responsible for inconsistent share of serious public health impacts and often depend on health care services for help.
There have been many debates on disputes about how immigration is causing health impacts on the public and costing the United States on public health system. The inability of illegal immigrants to pay for medical insurance is no longer a problem affecting them, but is increasingly becoming an issue of national concern. The number of Americans without health insurance coverage rose to 49.9 million in 2010 from 49 million in 2009, accounted to 16.3% of the US population.
In US the health care facilities are mainly provided by private sectors though state, federal and local governments also own some welfare programs like Medicare, Medicaid, State Children’s health insurance program etc. For the fiscal year 2011, the total budget government spending expenditure is $6.0 trillion, out of which $1.1 trillion was allocated to health care system. Most of the health care programs provided by the government have restricted eligibility with limited services rendered to the public through them.
