With an estimated twelve million illegal immigrants living in the U.S. it has been suggested that a national ID card would be the most accurate and convenient means to separate citizens from immigrants and legal immigrants from illegal immigrants. Countries all over the world depend on immigrants, who often take jobs that citizens do not want. Immigrants bring to their new countries both talent and ambition, along with youth and energy, all necessities of growing economy. But illegal immigration causes imbalance and undermines the natural immigration process. And now that the number of immigrants are at a historic high, and the economy is the worst it’s been since the great depression, many Americans blame the illegal immigrants for many of the nation’s problems. However, while many U.S. citizens believe that something should be done about the high number of illegal immigrants living in the U.S., few citizens like the idea of a national ID card. Those who oppose the idea of a national ID card often argue that attempts by the federal government to keep track of U.S. citizens as an invasion of privacy, even as most citizens are already being registered in many other ways, such as by security cameras and ATM bank machines. The reluctance of many Americans toward the notion of a national ID card seems to be one more obstacle in the way for President Barack Obama’s sought-after immigration reform.
