I grew up in San Jose. There were Asians most of them were well assimilated Japanese and Chinese who's families immigrated before 1930. Weren't that many maybe 1 out of 10.
The big immigration came later in the 1980's with the end of the Vietnam war/killing fields, and opening of China. A lot of ethnic Chinese in South East Asia fled in the 1970-80's.
India was quite closed off until relatively recently its only in the mid 80's that India began to compete when it abandond soviet style central control. "you can have any car you like as long as its a hundistan ambassador"
