Gov. Rick Snyder of Michigan on Thursday announced plans to seek federal help in bringing 50,000 immigrants to the bankrupt city over five years as part of a visa program aimed at those with advanced degrees or exceptional abilities in science, business or the arts.

Under the plan, which is expected to be formally submitted to federal authorities soon, immigrants would be required to live and work in Detroit, a city that has fallen to 700,000 residents from 1.8 million in the 1950s.

“Isn’t that how we made our country great, through immigrants?” said Mr. Snyder, a Republican, who last year authorized the state’s largest city to seek bankruptcy protection and recently announced plans to open a state office focused on new Americans.

Later, he added, “Think about the power and the size of this program, what it could do to bring back Detroit, even faster and better.”
