I'd like to know how many international employees (non U.S. citizens)
are working in the Denver metro area.

"Government statistics on foreign workers are incomplete. But the
Immigration and Naturalization Service said this week that 28,000
skilled foreign workers were approved for visas during the last three
months of 2001, down from 50,000 during the same period a year
earlier, when employers were rushing to submit applications before a
fee increase took effect.

The 28,000 are in addition to the 163,000 applications the INS
approved in the fiscal year that ended Sept. 30 -- including six
months when, economists say, the recession was in full force."

"Georgetown University scholars estimate that as many as 710,000 H-1B
permit holders are in the United States. "
