Brijesh Patel, who has worked in California's Silicon Valley for 12 years, is contemplating relocating to his home town in Bangalore in south India. The 39-year-old computer engineer fears that the new US administration's proposed radical changes to immigration policies will unleash protectionist, anti-immigrant and anti-minority havoc in a country that more than 2 million Indians call home. Even though Patel has a family in the US and plenty of Indian workmates, he says he and his friends have started seriously considering moving back.
