Immigrants don't pay taxes.
Immigrants pay taxes, in the form of income, property, sales, and taxes at the federal and state level. As far as income tax payments go, sources vary in their accounts, but a range of studies find that immigrants pay between $90 and $140 billion a year in federal, state, and local taxes. Undocumented immigrants pay income taxes as well, as evidenced by the Social Security Administration's "suspense file" (taxes that cannot be matched to workers' names and social security numbers), which grew by $20 billion between 1990 and 1998

In addition to the consumer spending of immigrant households, immigrants and their businesses contribute $162 billion in tax revenue to U.S. federal, state, and local governments. While it is true that immigrants remit billions of dollars a year to their home countries, this is one of the most targeted and effective forms of direct foreign investment.

The largest wave of immigration to the U.S. since the early 1900s coincided with our lowest national unemployment rate and fastest economic growth. Immigrant entrepreneurs create jobs for U.S. and foreign workers, and foreign-born students allow many U.S. graduate programs to keep their doors open. While there has been no comprehensive study done of immigrant-owned businesses, we have countless examples: in Silicon Valley, companies begun by Chinese and Indian immigrants generated more than $19.5 billion in sales and nearly 73,000 jobs in 2000. In addition to the consumer spending of immigrant households, immigrants and their businesses contribute $162 billion in tax revenue to U.S. federal, state, and local governments. While it is true that immigrants remit billions of dollars a year to their home countries, this is one of the most targeted and effective forms of direct foreign investment.

During the 1990s, half of all new workers were foreign-born, filling gaps left by native-born workers in both the high- and low-skill ends of the spectrum. Immigrants fill jobs in key sectors, start their own businesses, and contribute to a thriving economy. The net benefit of immigration to the U.S. is nearly $10 billion annually. As Alan Greenspan points out, 70% of immigrants arrive in prime working age. That means we haven't spent a penny on their education, yet they are transplanted into our workforce and will contribute $500 billion toward our social security system over the next 20 years.

The percentage of the U.S. population that is foreign-born now stands at 11.5%; in the early 20th century it was approximately 15%. Similar to accusations about today's immigrants, those of 100 years ago initially often settled in mono-ethnic neighborhoods, spoke their native languages, and built up newspapers and businesses that catered to their fellow émigrés. They also experienced the same types of discrimination that today's immigrants face, and integrated within American culture at a similar rate. If we view history objectively, we remember that every new wave of immigrants has been met with suspicion and doubt and yet, ultimately, every past wave of immigrants has been vindicated and saluted.

No security expert since September 11th, 2001 has said that restrictive immigration measures would have prevented the terrorist attacks-instead, the key is effective use of good intelligence. Most of the 9/11 hijackers were here on legal visas. Since 9/11, the myriad of measures targeting immigrants in the name of national security have netted no terrorism prosecutions. In fact, several of these measures could have the opposite effect and actually make us less safe, as targeted communities of immigrants are afraid to come forward with information.
