The Right Road to America?

First, it neglects the indispensable role that immigrants have played in building American wealth and power. In the 19th century, the United States would never have become an industrial and agricultural powerhouse without the millions of poor Irish, Polish, Italian and other newcomers who mined coal, laid rail and milled steel. European immigrants led to the United States' winning the race for the atomic bomb. Today, American leadership in the Digital Revolution -- so central to our military and economic preeminence -- owes an enormous debt to immigrant contributions. Andrew Grove (cofounder of Intel), Vinod Khosla (Sun Microsystems) and Sergey Brin (Google) are immigrants. Between 1995 and 2005, 52 percent of Silicon Valley start-ups had one key immigrant founder. And Vikram S. Pundit's appointment to the helm of CitiGroup last Tuesday means that 14 chief executives of Fortune 100 companies are foreign-born.

The United States is in a fierce global competition to attract the world's best high-tech scientists and engineers -- most of whom are not white Christians. Just this past summer, Microsoft opened a large new software development center in Canada, in part because of the difficulty of obtaining U.S. visas for foreign engineers.

Second, anti-immigration talking heads forget that their own scapegoating vitriol will, if anything, drive immigrants farther from the U.S. mainstream. One reason we don't have Europe's enclaves is our unique success in forging an ethnically and religiously neutral national identity, uniting individuals of all backgrounds. This is America's glue, and people like Huntington and O'Reilly unwittingly imperil it.

Nevertheless, immigration naysayers also have a point.

America's glue can be subverted by too much tolerance. Immigration advocates are too often guilty of an uncritical political correctness that avoids hard questions about national identity and imposes no obligations on immigrants. For these well-meaning idealists, there is no such thing as too much diversity.

The right thing for the United States to do -- and the best way to keep Americans in favor of immigration -- is to take national identity seriously while maintaining our heritage as a land of opportunity. U.S. immigration policy should be tolerant but also tough. Here are five suggestions:

¿ Overhaul admission priorities. Since 1965, the chief admission criterion has been family reunification. This was a welcome replacement for the ethnically discriminatory quota system that preceded it. But once the brothers and sisters of a current U.S. resident get in, they can sponsor their own extended families. In 2006, more than 800,000 immigrants were admitted on this basis. By contrast, only about 70,000 immigrants were admitted on the basis of employment skills, with an additional 65,000 temporary visas granted to highly skilled workers.

This is backwards. Apart from nuclear families (spouse, minor children, possibly parents), the special preference for family members should be drastically reduced. As soon as my father got citizenship, his relatives in the Philippines asked him to sponsor them. Soon, his mother, brother, sister and sister-in-law were also U.S. citizens or permanent residents. This was nice for my family, but frankly there was nothing especially fair about it. Instead, the immigration system should reward ability and be keyed to the country's labor needs -- skilled or unskilled, technological or agricultural. In particular, we should significantly increase the number of visas for highly skilled workers, putting them on a fast track for citizenship.

¿ Make English the official national language. A common language is critical to cohesion and national identity in an ethnically diverse society. Americans of all backgrounds should be encouraged to speak more languages -- I've forced my own daughters to learn Mandarin (minus the threat of chopsticks) -- but offering Spanish-language public education to Spanish-speaking children is the wrong kind of indulgence. "Native language education" should be overhauled, and more stringent English proficiency requirements for citizenship should be set up.
