I'm accepted by an dept but they do not have any fundings for international phd students at all. Can anyone tell me where i can get some fundings apart ors? Thx

I mean that it seems there are some orgnizations give some fanancial supports, and there are some student loan companies, but the information is just so much and I don't know where to start.

Information on funding for overseas research students is indeed confusing, which is why you'll find it difficult to find a clear answer on this forum. Other than the ORS scheme, which pays the difference between home and overseas fees, funding is largely dependant on your home country. Contact your own department of education or the British Council in your home country or, if appropriate, the association of commonwealth universities. Remember also to ask your new university to investigate any specific schemes which may be appropriate to you.
