In the letter, committee chairman Keith Vaz, the senior British MP of Asian origin, asked Singh whether New Delhi had been consulted by London while drafting the visa-bond proposal and for an outline of the Indian government’s position on the issue.
According to the British government, the visa-bond will be enforced as a year-long pilot beginning in November.
Under the pilot, high-risk visitors — those who are most likely to overstay their visa - from India, Nigeria, Ghana, Pakistan, Bangladesh and Sri Lanka will have to furnish a £3,000-bond.
The money will be returned when they leave Britain.
Also the Nigerian Ambassador to Britain has written to Vaz saying his country is “not favourably disposed to the proposal as it will affect a good number of Nigerians visiting the UK, even in spite of assurances to the contrary.”
“We view it as discriminatory and targeted at only non-white members of the Commonwealth,” Ambassador Dalhatu Sarki Tafida said.
