I am a graduate of 2009 and want to support the west, but I applied for a student loan. Can the loan be extended?

It depends on what kind of student loan you are. If not, you can repay the student loan first, and then repay this part of the loan after aiding Tibet. But as far as I know, the country will have many favorable policies to help Tibet, so you need to fully understand them. Moreover, aiding Tibet is not a matter of one or two days. Maybe stay there if you like in the future.
