(NewsNation) — President-elect Donald Trump is expected to fulfill the crackdowns he’s long promised on securing the U.S. border by signing multiple executive orders around immigration on his first day in office.

Trump ran a campaign largely focused on immigration and the southern border, saying he would order the largest mass deportation in American history of people who crossed illegally.

“The border security measures I will outline in my inaugural address tomorrow will be the most aggressive, sweeping effort to restore our borders the world has ever seen,” Trump told attendees of a private dinner on Sunday.

Trump is expected to sign these executive orders around the border Monday afternoon:

Trump to declare national emergency at southern border 

This order would help the secretary of defense quickly and seamlessly deploy members of armed forces to the border and free up more federal resources.

Trump to reinstate ‘Remain in Mexico’ policy

During his first term, Trump implemented the “Remain in Mexico” policy, also called “Migration Protection Protocols,” which required asylum-seekers to stay in Mexico until their claims were processed. Democratic President Joe Biden’s administration ended the policy in 2022.

Under the order, this policy would be reinstated.

Trump to end ‘catch-and-release‘ program

“Border czar” Tim Homan said the Trump administration will be ending the federal “catch-and-release” program, which allows immigrants who entered the country illegally to remain in the country as long as they are in the process for asylum.

“Stay in your homeland,” Homan told NewsNation last month. “Be safe. Crossing into this country illegally is very dangerous.”

Trump to resume construction on southern border wall

Trump began construction of the southern border wall during his first administration in an effort to prevent illegal crossings. Under the order, work would resume.

Trump to designate cartels as global terrorists

After being elected, Trump revived a campaign vow to designate Mexico’s drug cartels as terrorist groups.

“I will immediately designate the cartels as foreign terrorist organizations,” Trump said.

While in office in 2019, Trump dropped the plan at the request of Mexico’s then-President Andres Manuel Lopez Obrador, who said he wanted U.S. cooperation on fighting drug gangs.

Trump to suspend refugee resettlement

Trump, who put tight limits on refugees in his first term, has vowed to “suspend refugee resettlement” for four months as part of a broader effort to “immediately end the migrant invasion of America.”

The U.S. Refugee Admissions Program has brought in more than 3 million people since it was created by Congress in 1980 for refugees fearing persecution because of their race, religion, nationality, membership in a social group or political opinion.

Trump to end birthright citizenship

The president said he would end birthright citizenship, the right of children born in the U.S. to claim citizenship regardless of their parents’ immigration status. The 14th Amendment guarantees American citizenship to anyone born in the U.S.

Only constitutional amendments, not executive orders or legislation, can change the Constitution. Trump said he intends to issue an executive order to end the practice, though executive orders cannot overturn constitutional amendments.

Trump to direct military to prioritize borders

White House officials said the order would “clarify the military’s role in protecting the territorial integrity of the United States” by sending military personnel to the border, pushing the Department of Defense to erect barriers and green-lighting the use of drones and other surveillance measures.

Trump to enhance vetting, screening

Under this order, the president is expected to tighten up the vetting and screening of migrants entering the country.
