Worrying about money problems can have a very negative effect on your studies. You should tell your institution that you are having difficulties. The first step is to explain your problem to someone. You should try to speak your International Student Adviser, your academic tutor, your Welfare Officer, or someone at your Students' Union. They may be able to suggest ways of dealing with the problem and give you helpful information and advice.
It is important that you speak to an experienced adviser as early as possible and, especially, before you try to obtain financial help yourself. Their advice could help you avoid wasting time trying unrealistic sources and, therefore, endangering your student immigration status.
Advisers do not have large amounts of money available to help you pay tuition fees or living costs. There may be an institutional Hardship Fund or Access to Learning Fund but these are not available in all institutions. If they are available, the amount of money you can receive is usually low and limited to one payment.
If the financial hardship has been avoidable (for example, if you started the course knowing that you did not have enough money or that the funds from home would not last), there is probably nothing an adviser can do. You might have to consider returning home.
However, if something unexpected has happened, particularly in the last few months of a course, then the adviser can discuss your situation with you. They can help you choose the best alternative from your range of options.
