On Friday President Donald Trump took his most extensive step yet toward overhauling the US legal migration system, with a pair of proclamations that explicitly favor the wealthiest of the world's prospective expat workers. The US President slapped a $100,000 application fee on the widely used H-1B visa program, a move that would drastically increase the cost of visas heavily coveted by some of America's largest companies seeking to bring in skilled workers from abroad. CEO and Founder of Ark Invest Cathie Wood joined Caroline Hepker and Joumanna Bercetche on Bloomberg Radio to discuss the news as well as other trends driving markets.
