The change will affect the spouses of people with so-called H-1B visas, a limited-term working visa that employees obtain when they are sponsored by their companies.
As it stands now, their spouses only get a "dependent" H-4 visa which allows them to live in the US but not to work.
When spouses cannot work foreign families tend not to settle in the United States, depriving it of many workers highly skilled in science and technology.
Under the changes, spouses of people with H-1B visas who have applied for permanent residency 'green cards' can also apply for permission to work.
"The proposals announced today will encourage highly skilled, specially trained individuals to remain in the United States and continue to support US businesses and the growth of the US economy," said Deputy Secretary of Homeland Security Alejandro Mayorkas.
"The fact is, we must do more to retain and attract world-class talent to the United States and these regulations put us on a path to doing that," said US Commerce Secretary Penny Pritzker.
