Still the politics may yet be complicated in Detroit, a mostly black city where 38 percent of people live below the poverty level. “There will be some whose vantage point is going to be: ‘O.K., but what are you going to do to help the people who are already there?’ ” said Eric Foster, a political consultant in Detroit.

The Rev. Charles Williams II of the civil rights group National Action Network said he believed Detroit, as well as other Midwestern states, should be pro-immigration. “However,” he said, “I will say, on the other end of this, I think it’s a little ambitious for Governor Snyder to put together a plan to induce more population when still we have to work on double-digit unemployment and high poverty that’s already in our city right now.”

But advocates of bringing an influx of immigrants into the city say the outcome will ultimately benefit longtime residents, too, bringing new business enterprises and jobs, as well as a more stable tax base. “They’re going to have jobs as part of this process but the part you should focus in on, in particular, are all the jobs they’re going to create for Detroiters, for Michiganders,” Mr. Snyder said.

Under Mr. Snyder’s proposal, 5,000 immigrants would be granted visas in the first year to live and work in Detroit, under a program known as EB-2, in which federal authorities are permitted to grant a maximum of 40,040 such visas nationwide each year. Over the following four years, the number of visas for Detroit-based immigrants with advanced degrees or exceptional ability would go up, ending with 15,000 in the fifth year.

Mr. Snyder said demand already exists for experts in fields like engineering, technology and health care. And he noted that Michigan colleges and universities are home to tens of thousands of international students — many of whom, he said, ought not depart after graduation.

Representatives for Mr. Snyder said the governor had already had high-level discussions with federal officials about the concept but had yet to submit a formal request. Federal authorities said it was too soon to comment on it.

But a White House official issued a statement about the administration’s broad views, which said, in part, “President Obama is committed to honoring our nation’s legacy of innovation and competitiveness by attracting the world’s best and brightest students and entrepreneurs to start the next great companies here in the United States.”
