Construction of a border wall between the US and Mexico should begin in months and the Department of Homeland Security will begin the process of tracking down an estimated 11 million illegal immigrants, living in the US, from other countries.

The pair of directives signed today would also create more detention centers, add 10,000 immigration officers and an additional 5,000 border patrol agents. Trump’s actions also include measures to intensify deportations and workplace raids.

In addition, Vice President Pence swore in retired Marine Gen. John Kelly as the new Director of the DHS. Kelly is expected to begin study ways of denying some federal dollars to cities that harbor or refuse the detain illegal immigrants, known as Sanctuary Cities.

Trump also gave greater power to some local authorities to enforce immigration violators, under the Secure Communities Program.

Press Secretary Sean Spicer said Trump “would not sign any orders overturning the Obama Administration’s Deferred Action for Childhood Arrivals program that has allowed more than 700,000 younger immigrants brought to the country illegally as children to apply for two-year work visas,” the Washington Post reported.

Some see the move as turning away genuine asylum seekers and are against a mandate to detain families with children, but an advocacy group that represents families of victims who were killed by illegals, calls it justice.
