Financial planning for language school.

Hello everyone! I am planning on enrolling in a Japanese language school this October but i have a slight hiccup and would like your opinion on it.

Context:

I am 24M with a university degree and jft basic certificate(~JLPT N4)

Total income of my parents is about $30,000 but they don’t have much liquid funds as they like to invest most of it in assets.

My dad will retire in September.

I am planning on applying for a student loan.

What should i do to increase my chances of getting the coe.

Do i have any other options ?

Thanks a lot for your time !!!
