For migrants to the UK from India and elsewhere, the grass might not be greener on the other side, a new study from the University of Leicester has found. 

The probable reason: migrants expect to be happier by virtue of earning the greater incomes available in a wealthy country, but they end up wanting even more after they get there. Aspirations probably increase at least as much as incomes.

The partnership has been inked between India's Department of Bio-Technology and the Wellcome Trust.
