Trump restat­ed his plans to build a wall and oth­er phys­i­cal bar­ri­ers along the south­ern bor­der and detain immi­grants sus­pect­ed of vio­lat­ing the law. The order called for fed­er­al-state part­ner­ships to enforce immi­gra­tion poli­cies. It also changed parole poli­cies by ceas­ing the CBP One appli­ca­tion, a free mobile appli­ca­tion, which allowed undoc­u­ment­ed immi­grants to sched­ule appoint­ments, sub­mit infor­ma­tion and enter the U.S. through land ports of entry. The “Process­es of Cubans, Haitians, Nicaraguans, and Venezue­lans” pro­gram was also halt­ed start­ing March 25. This was a parole pro­gram that allowed peo­ple from these coun­tries to tem­porar­i­ly live and work in the U.S.
