What Is The H-1B Visa, And Why Does Donald Trump Want To Kill It?

Republican presidential candidates sought to outdo each other in Thursday’s debate when it came to reforming the H-1B visa, a controversial program through which Silicon Valley giants like Facebook, Apple and Hewlett-Packard import skilled help from India and other countries with vast pools of low-cost tech talent on tap.

GOP frontrunner Donald Trump said the H-1B hurts American-born workers and said that he would end it outright. Marco Rubio said the program needs to be better policed, while Ted Cruz simply said the U.S. needs to update its immigration laws for the 21st century.
