America’s immigration policy is “the craziest thing in the world,” Mayor Bloomberg said during a visit to Google’s 300,000-square-foot offices in Chelsea early yesterday.

“Everybody else is trying to get the best and the brightest and we’re trying to keep them out,” the mayor said. “It doesn’t make any sense.”

The mayor laid out his solution to the immigration question, calling for better enforcement of laws, so employers don’t hire undocumented workers, and a plan to grant permanent status to the 12 million illegal immigrants residing in America. Mr. Bloomberg suggested Social Security cards be improved to include biometric anti-fraud measures that would make it easier to verify workers’ legal status. He also said America should issue 500,000 or more visas each year.

“If you had companies only employing people who were documented you would not have this big influx of people overstaying their visas or coming across the border,” Mr. Bloomberg said.

The mayor said illegal workers commit crimes at a low rate and do not drain public services because they avoid government programs out of fear of being deported.

“Everybody has this misconception of undocumented workers using an enormous number of services, which costs us a lot, and contributing nothing, and the truth of the matter is it’s exactly reversed,” he said.

Comptroller William Thompson Jr. also announced yesterday that he is calling on Google and Yahoo to uphold the United Nations’s declaration of human rights and establish policies that protect the “basic freedoms” of Internet uses around the world.
