The Trump administration’s executive orders on immigration and the environment are set to make it easier for the government to stop some people from returning to the US after they have lived here for years, according to new research from the University of Minnesota.

The research found that the order could have unintended consequences for economic growth.

“The order could reduce economic growth by limiting entry for people who already have visas and other benefits, and it could increase uncertainty about whether the visas are valid or have been issued in the past,” said University of Minneapolis economics professor Brian Doherty, a co-author of the research.

The study, which was published online in the journal Economic Inquiry, used a combination of interviews and data from a federal database to find out what would happen to a country if the orders were implemented, and if there was any effect on the economy.

The order is expected to be signed by President Donald Trump on Friday, with the first executive order being issued on Jan. 27.

The second executive order is slated to be issued in late January.

While the first order temporarily bans immigration from seven majority Muslim countries, the second order has been delayed for months by legal challenges.

Trump’s executive action was supposed to have the largest impact on green card holders, and the second executive is expected have a much smaller impact, according a spokeswoman for the Department of Homeland Security, Heather Fritz.

The Trump administration is also taking steps to curb greenhouse gas emissions from the coal industry.

The executive orders will be enforced through the Environmental Protection Agency and the Bureau of Land Management, which would continue to enforce federal laws.

It is unclear how the new orders will affect the environmental enforcement system in the Interior Department.
