The study of the attitudes of 3,100 international students by the National Union of Students shows that more than 50 per cent believed the UK Government was either "not welcoming" or "not welcoming at all towards overseas students".
Figures in the survey released yesterday showed PhD students are most likely to feel unwelcome (65.8 per cent) with those from Japan (64.5 per cent), Nigeria (62.8 per cent) and India (62 per cent) the next most likely to say they have received hostile treatment.
Asked what most perturbed them, 40 per cent cited moves to get landlords to check on their legal status - while 74 per cent said introducing an National Health Service levy would make it either impossible or more difficult to study in the UK, the survey said.
Student leaders argue the figures are "extremely worrying" as international students are estimated to contribute over 7.9 billion pounds a year to the UK economy, the report in the daily said.
