Prime Minister Narendra Modi arrived at the SAP Center for a Madison Square Garden-like reception by the Indian community here.
"A Madison Square Garden moment for Silicon Valley. The SAP Center is jampacked as PM @narendramodi arrives," tweeted external affairs ministry spokesperson Vikas Swarup.
Modi had last year got a rockstar like reception at New York's Madison Square Garden.
More than 45,000 people have registered for free passes for the event at the 19,000-seat SAP Centre organised by an Indian American group.
