How do I convince my parents to let me go to america?

My parents are getting really edgy bout the fact that I want to move to America, I'm nearly 19, they keep asking why America, and I've grown up knowing a lot of Americans, and I think America as a country is an amazin place and sure I may not agree with the government at times, but they cant seem to understand why I'm so desperate to go there, Everything I heard about America growing up was how great it was, How can I convince them to let me go

Thats such a big step.
Going from living at home with your parents, to living in a whole other country seems like a bit much. Maybe you should take smaller steps, and maybe move out but stay in your own town for a while. Moving out is a lot of new responsibilities and it would be nice to have your parents near the first time you move out in case you need something. If you take that huge step moving to America right away, your parents wont be able to help you out. I'm also almost 19-years-old and I'm not even ready to move out at all, let alone to a whole other country. Think about it...

Determine what your dreams are / what's in your best interests - visits back and forth are not impossible...whatever you decide, I wish you every happiness !!

trust me, you dont want to go to america, this place is polluted inside and out. if you dont believe me, go ahead and try, but take it from someone who knows.
