[LAB] The article focuses on the obstacles to legal immigration imposed by the Trump administration against those who are already in the US pursuant to their valid non-immigrant classification and those who are abroad and trying to reunite with family members in the US or seeking entry having a legitimate job offer from a US employer. Recent changes in US immigration policy have been achieved through restrictive interpretation and enforcement of existing law by the USCIS which is part of the Department of Homeland Security, and by the State Department (DOS) rather than by substantive legislative changes done in Congress. The article provides an overview of the most recent governmental restrictions affecting so called “business immigration” and family-based immigrant processing, and also restrictions on suspension of entry to the US due to Covid-19, introduced through presidential proclamations. Although the federal courts blocked several of these administrative initiatives, the anti-immigrant atmosphere is having a big negative impact on many groups of foreign nationals.  Nationalistic notions of “making America great again” that should be accomplished through “buy American and hire American” principle, and legal uncertainty causing ongoing federal lawsuits will undoubtedly lead to America’s further isolationism if President Trump wins the November 2020 election.
