Donald Trump's companies have sought visas to import at least 1,100 workers

Donald Trump is staking his run for U.S. president in part on a vow to protect American jobs. But this month, one of his companies, the elite Mar-a-Lago Club resort in Florida, applied to import 70 foreign workers to serve as cooks, wait staff and cleaners. Trump owns companies that have sought to import at least 1,100 foreign workers on temporary visas since 2000, according to U.S. Department of Labor data. Most of the applications were approved.
