Donald Trump in the White House could spell the end of the J-1

Trump is the current frontrunner among candidates for the Republican nomination despite a string of gaffes and criticism of comments aimed at women and migrants.
His campaign website, donaldtrump.com, lists a range of policies he would seek to implement were he to be voted into the Oval Office, including a requirement firms hire Americans first, ahead of job candidates of other nationalities, and the mandatory return of all foreign nationals with a criminal conviction.
