The Department of Justice (DOJ) and Department of Homeland Security (DHS) announced a new rule Monday, moving to end asylum protections for most Central American illegal migrants.

According to a new rule published in the Federal Register, asylum-seekers who cross through another country before arriving to the United States will be ineligible for asylum when they reach the southern border.

Attorney General Bill Barr released the following statement regarding the rule: “The United States is a generous country but is being completely overwhelmed by the burdens associated with apprehending and processing hundreds of thousands of aliens along the southern border. This Rule will decrease forum shopping by economic migrants and those who seek to exploit our asylum system to obtain entry to the United States—while ensuring that no one is removed from the United States who is more likely than not to be tortured or persecuted on account of a protected ground.”

Acting Homeland Security Secretary Kevin McAleenan described the rule as an “interim” measure until Congress can act.

“Ultimately, today’s action will reduce the overwhelming burdens on our domestic system caused by asylum-seekers failing to seek urgent protection in the first available country, economic migrants lacking a legitimate fear of persecution, and the transnational criminal organizations, traffickers, and smugglers exploiting our system for profits,” McAleenan said in a statement.

The ruling is based on provisions in the Immigration and Nationality Act, which states that migrants denied asylum will be sent back to the nation they crossed, and that migrants can not resettle in another country and then return to the United States to seek asylum, according to Daily Caller.

A migrant may also still qualify for asylum in the United States if they register in another nation but are refused refuge or are a victim of serious human trafficking.

The ruling is to restrict protections for most Central American asylum-seekers, and is expected to go into effect Tuesday. 

This year, the United States has encountered an unprecedented number of refugees crossing the southern border, resulting in overcrowding in detention centers and a backlog in immigration judiciary. The situation has been called a humanitarian and national security crisis by President Donald Trump.
