I dont know what to do?

Hey bro I'm also an immigrant with working parents. I know how it feels. My advice is - don't go for the air force. You can do better than that. I know it's exciting and fun but think about your working parents. I'm pretty sure they aren't OK with this idea. If you can't afford this college - get out. Of course it's fun to waste your time there but you'll also waste money. If you are a low income family, you can get Federal Pell grant( about 5,500$ a year) for your education. Go to community college and use this pell grant. this will make it free. even if you can't get pell grant, community colleges are very cheap to pay for. everyone can go there no matter what your grade is. By the way, where are you from?? :D
