US President Barack Obama is due to attend a town hall-style meeting with young people in Delhi on the final day of his visit to India.
The three-day tour has been aimed at boosting economic ties between the two major allies.
Speaking at a joint business forum in Delhi on Monday, Mr Obama said there was "much untapped potential" in the US-Indian economic relationship.
He also attended India's Republic Day military parade.
On Sunday, the first day of his visit, Mr Obama and Indian Prime Minister Narendra Modi announced a breakthrough on a pact that will allow US companies to supply India with civilian nuclear technology.
The historic 2006 India-US nuclear deal had been held up for eight years amid US concerns over who would be liable for any nuclear accident. Mr Singh, the deal's architect, had told the parliament that it marked the "end of India's decades-long isolation from the nuclear mainstream".
Now, a large insurance pool will be set up, without the need for any further legislation. The plan, according to reports, is to transfer the financial risk to insurers in the case of an accident.
Analysts say the two governments have done "all they can do" and it is now up to the suppliers - or American firms wanting to sell reactor technology to India - to do business.
Will the India-US nuclear deal work?

Mr Obama said a strong US-India relationship was a "win-win" situation
At the business event on Monday evening, both he and Mr Modi hailed the bilateral progress, with the Indian leader saying a stronger relationship "will make this world a better place for all".
Mr Obama said trade had grown by around 60% in the past few years which was a "win-win" situation.
"We're moving in the right direction," he said. "That said, we all know that the US-India economic relationship is also defined by so much untapped potential."
Mr Obama's visit to India has been shortened so he can visit Saudi Arabia and pay his respects following the death of King Abdullah. It means he and his wife, Michelle, will not now visit the Taj Mahal.
