Statistics obtained by the BBC as part of a freedom of information (FOI) request indicate severe NHS staff shortages with a majority of NHS trusts across Britain forced to turn overseas to countries like India and the Philippines.
However, visa changes over the years and some proposed changes expected to kick-in soon have been making the British medical system less attractive for Indian doctors.
The group had recently taken up the issue of the UK's plans to impose a new Resident Labour Market Test (RLMT) to give UK and European medics priority in the UK job market.
"It will be very unfortunate as the NHS is already suffering from huge shortage of doctors and unwise regulations will only create further problems," Mehta noted.

In contrast, the number of new Indian doctors registering with the General Medical Council (GMC) in the UK dropped from 3,640 in 2004 to just 534 last year.
The Royal College of Nursing and the British Medical Association blamed poor workforce planning for the problems.
A Department of Health statement said: "Staffing is a priority - that's why there are already over 29,600 extra clinical staff, including more than 10,600 additional doctors and more than 10,600 additional nurses on our wards since May 2010. There are more than 50,000 nurses currently in training.
"That's why we are changing student nursing, midwifery and allied health professionals funding to create up to 10,000 more training places by the end of this Parliament."
The NHS has historically turned to the Indian sub-continent to meet staff shortages as well to increase the headcount ofdoctors and nurses and claimed that "foreign health workers make a valuable contribution to the NHS".
