The federal government on Friday proposed new rules that would allow people to travel to the US for the first time in nearly 30 years without a visa.

The changes would require travelers to show they are a “high-risk” individual who poses a “serious threat” to national security, and would allow them to cross the border without a valid visa.

A senior administration official said the new regulations are designed to “improve the safety and security of Americans traveling abroad.”

The move comes as Trump has been working to shore up support among Republican voters ahead of next month’s midterm elections.

The Trump administration also has pushed through several travel restrictions in recent days.

It has blocked people from Iran and Libya from traveling, while restricting people from entering the U.S. by sea and by land.

It also has stopped U.K. citizens from traveling to the U, Canada, Australia, South Korea, China and the European Union.

In addition, the administration has imposed restrictions on travelers from North Korea, Syria and Iraq, while temporarily blocking travel to Iran.

Those restrictions are designed as temporary measures until the Trump administration can come up with a permanent solution.

They are part of a broader effort to rein in what some say is a surge of terrorism linked to the travel ban.

A federal judge on Friday temporarily blocked parts of the travel order and ordered the administration to respond to the court.
