Washington DC - India is prepared to take back its citizens residing without documentation in the US, foreign minister Subrahmanyam Jaishankar has said after meeting the top diplomat of President Donald Trump's new anti-migrant administration.

Jaishankar's remarks came after a meeting with US Secretary of State Marco Rubio in Washington on Tuesday a day after Trump's inauguration.

Trump issued a raft of executive orders this week that aim to clamp down on immigration and expedite his goal of deporting millions of immigrants.

Jaishankar said New Delhi was open to taking back undocumented Indians and was in the process of verifying those in the US who could be deported to India.

"We want Indian talent and Indian skills to have the maximum opportunity at the global level. At the same time, we are also very firmly opposed to illegal mobility and illegal migration," Jaishankar told a group of Indian reporters in Washington on Wednesday.

"So, with every country, and the US is no exception, we have always taken the view that if any of our citizens are here illegally, and if we are sure that they are our citizens, we have always been open to their legitimate return to India."

Jaishankar was responding to a query on news reports that India was working with the Trump administration on the deportation of around 18,000 Indian nationals who are either undocumented, or have overstayed their visas.

Rubio had "emphasized the Trump administration's desire to work with India to advance economic ties and address concerns related to irregular migration," State Department spokesperson Tammy Bruce said in a readout after Tuesday's meeting.

India is the world's fifth-largest economy and enjoys world-beating GDP growth, but hundreds of thousands of its citizens still leave the country each year seeking better opportunities abroad.

While its diaspora spans the globe, the US remains the destination of choice.

The most recent US census showed its Indian-origin population had grown by 50% to 4.8 million in the decade to 2020, while more than a third of the nearly 1.3 million Indian students studying abroad in 2022 were in the US.
