The Trump administration was handed another win on Thursday after a federal judge ruled that everyone in the U.S. illegally must register with the federal government and carry documentation.The Associated Press reported that Judge Trevor Neil McFadden, who was appointed by President Donald Trump, sided with the administration after arguing it was enforcing an existing requirement for everyone in the country who is not a citizen of the U.S.Rather than rule on the substance of the Trump administration’s arguments, McFadden ruled that the group pushing to stop the requirement did not have standing to pursue their claims.McFadden’s ruling will go into effect Friday.NOEM SENDS MESSAGE TO THOSE CONSIDERING ENTERING US ILLEGALLY: ‘DON’T EVEN THINK ABOUT IT’The Department of Homeland Security (DHS) said Thursday that the deadline to register for anyone who has been in the country for 30 days or more is Friday, adding that the registration requirement will be enforced to the fullest.”President Trump and I have a clear message for those in our country illegally: leave now. If you leave now, you may have the opportunity to return and enjoy our freedom and live the American dream,” DHS Secretary Kristi Noem said in the statement. “The Trump administration will enforce all our immigration laws — we will not pick and choose which laws we will enforce. We must know who is in our country for the safety and security of our homeland and all Americans.”The DHS began warning illegal immigrants in February that they should leave the country or face serious consequences.DHS SECRETARY NOEM APPEARS TO ACCUSE ‘CORRUPT’ FBI OF LEAKING LA ICE RAIDSThe secretary said DHS will enforce the Immigration and Nationality Act, which was enacted in 1952 and created several tools to track illegal aliens and compel them to voluntarily leave the U.S.DHS said the tools include criminal penalties for migrants who choose not to leave the U.S., fail to register with the federal government and get fingerprinted, and fail to notify the federal government of changes to their address.Illegal immigrants who fail to depart the U.S. will be charged with a crime resulting in a “significant penalty,” DHS said.NOEM ENDS BIDEN-ERA USE OF CONTROVERSIAL APP TO ALLOW MIGRANTS TO BOARD FLIGHTS, EXCEPT TO SELF-DEPORTBut migrants who fail to register with the federal government could be fined, imprisoned or both.Registration is mandatory for anyone 14 and older without legal status. Anyone registering will be required to provide their fingerprints and address.Canadians are also required to go through the registration process if they have been in the U.S. for more than 30 days – this includes “snowbirds,” who spend winter months in warmer areas like Florida.While it has long been required for people who live in the U.S. and are not American citizens, the requirement has only been enforced in rare circumstances.For instance, the requirement was enforced in a limited way after Sept. 11, 2001, when the National Security Entry-Exit Registration System required noncitizen males 16 and older from 25 countries – all but one of them Arab or Muslim – to register with the U.S. government.Even though the program did not lead to terrorism convictions, it pulled over 13,000 people into deportation proceedings. The program was suspended in 2011 and dissolved in 2016.The Associated Press contributed to this report.
