Foreign startups, investors fear tightened US rules

SUNNYVALE, the once sleepy orchard turned suburb city in the heart of Silicon Valley, is a relatively new home to major US tech giants, as they gobbled up vast expanses of office space here in recent years.

Bordered by San Jose to the north, Mountain View to the northwest and Cupertino to the south, Sunnyvale is also becoming a home to Korean startups and venture capital firms in search of local partners, customers and promising technologies.
