There have been "no big changes" in the H-1B programme and "nothing new" on the H-4 visa policy, the US said on Wednesday, amid the Trump administration's plan to overhaul the immigration system.

US deputy chief of mission (DCM) in Delhi, MaryKay L Carlson said granting employment visa and work permits is the sovereign decision of a country.

The US Mission here today observed 'Student Visa Day', an event to celebrate higher education ties between India and the United States.

"There have been no big changes in the H-1B programme and nothing new on H-4 ...," Carlson told reporters here.

Certainly, employment visa and work permits for Indians is the sovereign decision of the US, the official said.

The Trump administration's move to end the Obama-era rule could have an impact on more than 70,000 H-4 visas holders , who have work permits.

H-4 is issued to the spouse of H-1B visa holders, a significantly large number of whom are high-skilled professionals from India.

External affairs minister Sushma Swaraj had last month said the government would make all efforts to persuade the Trump administration against such a move.

In her annual press conference on May 28, the minister had said it was true that President Donald Trump was reviewing the H-4 visa programme and there were reports of its possible revocation.
On the occasion of 'Student Visa Day', the mission also dedicated the day to student visa applicants who have enrolled for higher studies in different US universities.

The US embassy in New Delhi and the consulate general of Chennai, Hyderabad, Kolkata and Mumbai, welcomed over 4,000 Indian students, who applied for visas to study in the United States.

In 2017, more than 1,86,000 Indian students were enrolled in US institutions for higher education, more than double the number from a decade ago and a 12 per cent increase from the year before.
