Trump is set to visit India on a two-day trip between February 23 and 26 and both sides are in the process of fine-tuning his schedule, sources said.
The main segment of the visit will take place in the national capital, though an option of having a short visit by Trump to another city is being explored.
The cities being considered include Agra and Ahmedabad.
A high-level logistics team from Washington handling Trump's foreign trips visited India last week as part of preparations for his maiden tour of India as the US president.
"The trade deal and a pact on further enhancing defence cooperation are likely to be sealed during the visit by the US president," said a source.
India is seeking exemption from high duties imposed by the US on certain steel and aluminium products as well as resumption of benefits on tariff on certain products under their Generalised System of Preferences (GSP).
