US Immigration Policy Changes Expected Under Biden Aline Barros WASHINGTON - The incoming administration of President-elect Joe Biden could swiftly reverse an array of President Donald Trump's immigration policies, many of which remain among the most contentious initiatives of his administration. Biden could overturn many guidelines using the same mechanism Trump employed to implement them: executive orders. Others, however, will require more than a policy declaration, experts say. In the last four years, Trump authored [1]more than 400 regulatory actions through his executive power. Michele Waslin, program coordinator at the Institute for Immigration Research at George Mason University in Virginia, told VOA the list includes sweeping travel restrictions, changed immigration enforcement priorities, overhauled asylum rules, an emergency declaration for border wall construction and successively reduced caps on refugee admissions. "In theory, presidential proclamations and executive orders can be rescinded by the new president; however, in many cases, the change will not be immediate since people will need to be installed in the agencies, guidance and field manuals must be updated, and plans will need to be made to carry out the changes," she said. Waslin said undoing other policies is expected to be more complex. "Policies that were changed through regulations will likely require new regulations and a new public comment period," she explained. The first 100 days Within the first 100 days, Biden is expected to repeal Trump's executive order that barred most nationals from certain countries from visiting the United States. Initially, the restrictions targeted citizens of some majority Muslim nations, but they were expanded to include other countries Washington regards as security threats.
