Nearly 1.8 million H-1B visas were distributed between 2001 and 2015. Designed to help employers hire highly skilled foreign workers, the program has come under fire. Last year the president signed an executive order to reform all employment based visa programs. Part of that crackdown could also strip employment authorization from the spouses of some H-1B holders. The change would mean that nearly 100,000 mainly Indian women could lose their right to work. Special correspondent Joanne Jennings reports from Silicon Valley, where tech companies rely heavily on these foreign workers.
