During his stay in the financial capital of the country for next two days, Modi will attend a roundtable on the financial sector, an important meeting with Foreign Institutional Investor (FII) keen to invest in India.
He will also headline a roundtable on media and communications hosted by News Corp's Rupert Murdoch and attend a dinner with Fortune 500 company CEOs in the Silicon Valley.
He would then fly to the West Coast for his visit to California from September 26-27.
"A packed schedule awaits in the Big Apple. PM @narendramodi arrives in New York on the first part of his US visit," Ministry of External Affairs spokesperson Vikas Swarup tweeted soon after Modi's plane touched down at the JFK International Airport here.
The Prime Minister was received at the airport by Indian Ambassador Arun K Singh, India's envoy to the UN Asoke Mukerji, Consul General Dnyaneshwar Mulay and their spouses.
Modi later arrived at the Waldorf Astoria hotel here to a grand welcome by his supporters. He will return to New York on September 28 for a bilateral meeting with President Barack Obama as well as to attend a high-level peacekeeping summit at the United Nations.
On Friday, he will address global heads of state at the Sustainable Development Summit hosted by UN Secretary General Ban Ki-moon when the new and ambitious post-2015 development agenda will be adopted.
India will also host the G-4 summit here on September 26, before Modi leaves for the West Coast for a two-day trip during when he will have meetings with Facebook CEO Mark Zuckerberg, Apple CEO Tim Cook and Google's new CEO Sundar Pichai.
He will also attend a grand community reception in San Jose. Modi will meet Barack Obama on September 28, his third summit meeting with the US President in about a year.
During his stay in the city, Modi will have meetings with French President Francois Hollande and heads of state from Bhutan, Sweden, Guyana and Cyprus, as well as the heads of state of Brazil, Japan and Germany at the G-4 summit on September 26.
Modi is expected to focus on giving a further push to early and urgent reform of the Security Council and to send an "unambiguous message" of "zero tolerance against terrorism".
Officials said Prime Minister Modi will not have a bilateral meeting with his Pakistani counterpart Nawaz Sharif during his current five-day trip to the US.
