I know that Rabindranath Tagore studied at University College London and some wealthy Indians studied in other British universities. How were they treated by other students or the general public?
There is always more to say, but I answered a very similar question here some time ago, focusing on the period from 1870-1947, and you might like to review that thread while you wait for fresh responses to your query:
I am a Indian who has come for higher education in United kingdom pre 1947 . How am I treated in UK?
