Some people here may object to what I am going to say, but that's their prerogative.
I have worked for years with local and international students and have found that, almost without exception, they find the University Chaplancies very helpful and sociable places.
It doesn't matter if you profess any religion or none at all - they are open to everyone. There are usually loads of social activities, and many students get involved in charities such as Habitat for Humanity or other overseas aid projects.
Many go abroad on teaching and building projects - that's how you meet decent people, not those who hang around bars and expect casual sex.
It's a fact of life that 'freshers' are always seen as an easy sex target - you are not cynical, but the guys who try to exploit you are.
Chaplancies are also very helpful if you are feeling a bit lost or low and don't want to go down the formal counselling road. There is always someone to listen and try to empathise, and remember - University Chaplains have heard it all before - and what you talk over with them is always confidential.
