The Indian government does not track the number of undocumented Indian immigrants residing in the US. Minister of State for External Affairs Kirti Vardhan Singh, in a written response to a query in the Rajya Sabha, said these immigrants have "legally exited India" but have either overstayed their visa validity, or have entered the US illegally or without valid documents. The response comes at a time when Prime Minister Narendra Modi is on a two-day visit to the US, during which he will hold a bilateral meeting with President Trump. The two leaders are likely to discuss India-US cooperation in sectors like trade, investment, energy, defense, technology and immigration.
