I am from India, and I grew up in childhood with a poor neighbour of mine, of the age of my parents. They took very good care of me, our economic disparity notwithstanding.
Now I am working in the UK on a tier-2 visa in a cushy job, and would like to bring them (a man and a woman) to the UK on a visitor visa. I can fully sponsor them and provide my bank statements and a written invite. However, this alone will not be enough I think. They need to convince the visa officer that they will return to India after the trip.
They do not have any assets or fixed deposits, nor any kids. Under such circumstances, is there any possibility to bring them over? Will a return flight ticket be a proof (I think not).
