After addressing an Indian community event at the SAP Centre here, Modi left for New York where he is scheduled to meet US President Barack Obama.
In the final engagement at the SAP Center here, reminiscent of the grand reception he was accorded exactly a year ago at Madison Square Garden in Big Apple, Modi left after announcing a "physical" connect between US's tech capital San Francisco and the Indian national capital New Delhi.
He announced a direct flight, twice a week, between the two cities from December 2 to be operated by India's flag carrier Air India. Modi, in fact, returned to the stage to make the announcement after he had ended his hour-long speech.
The prime minister had already impressed the top chief executives of some of the world's best-known technology companies with a quip that he was already in virtual touch with them and others in this tech hub through Facebook, Twitter and Instagram.
"Goodbye California! PM @narendramodi departs San Jose for New York, after a very productive weekend,"" tweeted external affairs ministry spokesperson Vikas Swarup.
