Restrictions on family migration were introduced by Home Office ministers as part of the drive to reduce net migration to Britain.
Under the new rules, a British citizen who wants to bring in their spouse or dependent from India or any other country outside the 30-member European Economic Area has to earn a minimum 18,600 British pounds a year.
The requirement rises to 22,400 British pounds to sponsor a child and 2,400 British pounds for every additional child.
Some UK sponsors were now considering leaving the UK, or had already done so, in order to care for their elderly relative overseas121.
A member of the medical profession in Scotland reported that a number of his colleagues were reconsidering their employment and were seeking to move their families (including British children) to India in order to look after elderly dependent relatives, the All-Party Parliamentary Group on migration said in its report.
The group concluded that the rules may have unintended consequences.
These include stopping high-earning non-EU spouses from living in Britain and supporting their families, as well as impacting on British citizens who work full-time but who do not earn above the minimum threshold.
"We found that, in today's internationally connected world, British citizens who are seeking to build a family with a non-EEA national -- including from the USA and from Commonwealth countries such as Australia, Pakistan and India -- are being prevented indefinitely from living together in their own country", the report said.
India forms 10 per cent of the total applications for immigration to the UK. Declines were shown across all of the top 20 nationalities for family visas, with the United States seeing the largest fall (-935), followed by Nepal (-678) and India (-605), Home Office data issued in May 2013
