A large crowd gathered outside the SAP Center in San Jose where Modi spoke in front of a crowd of at least 18,000 people.
Many people are protesting his visit to California and some are supporting it.
Modi supporters like his digital India plan to expand high-speed Internet to 80 percent of the country.
But Modi was also met by protesters who call the prime minister’s human rights record dismal. “His ideology means success for some, bur oppression for many. That manifests as cast oppression, gender violence,” Alliance for Accountability and Justice spokesperson Sabiha Badrai said.
