The visit of the US lawmakers reflected the growing bipartisan support for strengthening the Indo-US strategic ties and comes nearly a month after Donald Trump became the President.
The delegation is scheduled to meet senior Indian leaders during which they are likely to be apprised about India's apprehensions over the H1B visa.
During the visit from February 20-25, the lawmakers are scheduled to have a wide range of meetings with top government officials, politicians, members of think-tanks and non-governmental organisations.
Another bipartisan Congressional delegation (or Codel) of eight lawmakers, being led by Bob Goodlatte, Chairman of powerful House Judiciary Committee, is visiting India from February 20 to 23.

India's Ambassador to the US Navtej Sarna last week had said such a visit is reflective of the efforts on the part of the US to "strengthen and build" on the bipartisan support that they have in the US Congress for India-US relations.
Congressional records indicate that this is the largest ever travel of US lawmakers to India.
The delegation includes Congressman George Holding, Co-Chair of the India Caucus, Jason Smit and Dave Trott.
