Dear members,

Hope you are all doing well.
I came in uk as a student last year for MBA course.
I studied in a college affeliated with university of wales.
I have completed my course and have submitted my dissertation last week to university.
My current visa going to be expired on 30/10/2010.
My college is not giving me exact date when university will issue the reult card?
Can any one advice me please how can i extend my visa because i am not sure that i will get my results before 30/10/2010?

I will be appreciate your quick response.

THANKS...
IMRAN.........
