Student Exchange Programs

Is this possible to achieve without earning all the money (I can’t earn $9,000 from my job in less than 4 months) to go to Spain next spring. I was recently informed that asking for donations is illegal, but I’m confused why nearly every single foreign exchange program insists on asking for donations from businesses and such. I’m incredibly confused, can anybody help? Are all of those “success stories” just lies so that you will apply and then not be able to get all of your money back? Is that scamming kids out of their money cause it seems like that to me…

And if anybody can point me in the direction of some foreign exchange scholarships for high school students, I would owe you so much! Can I even apply for scholarships through programs other than the program that I am going with? (AYUSA)

Anybody’s advice on student loans for this type of thing? Can I even get them if I’m not 18 yet/don’t have my parent’s approval?

I am desperate to go abroad and I will do anything to go.
