Most of the modern discussion on
immigration policy is directed to the question of which aliens who enter into
the United States should be allowed a path to citizenship and why. In
dealing with that topic, Gary Becker and Edward Lazear have powerfully argued that a market
system is the best way to attract “people with skills and vision” into the
United States. That program is correct as far as it goes. But in a sense it
does not go far enough. Immigration policy cannot concern itself only
with the long and complex progression from entry to citizenship. It must
also deal with another reality of the modern integrated global economy, namely,
the way in which the United States—and for that matter other nations—admit
individuals on short-term work visas.
These visas are of immense importance
especially at the higher echelons of the workforce, for nothing is more common
today than for key employees in global firms to do short-term tours of duty in
the United States, even when they have no intention to seek permanent residence
or U.S. citizenship. In two important ways, these cases present far fewer
problems than do foreign entrants into the United States in search of permanent
status. Often these business entrants come with substantial income and
without families, and hence do not put the kinds of pressure on domestic social
support systems than do entrants with large families and limited levels of
support. In addition, since these workers do not aspire to citizenship, they
will not obtain the right to vote, which adds an important political dimension
to their entry into this country.
