Analou, you're still too young, just 18. Probably this guy who will sponsor you is a very "special" friend of yours right? May not be your boyfriend yet but getting on that stage. I advise that get to know him well, don't rush things. It's better to concentrate on your studies and finish your course.
But if you decided to push through an application just be extra careful because you are indeed too young and know little things about men. Just a sisterly advice from me.
