Most of chinese people want to go aboard, but few of them can make it. If you want to do it, you need to prepare a lot of things, such as language and passport. And it will be easier for you to go to England than America. Most of those foreign countries need the people who can make contribution for them, if you don't have a lot of money, you should be excellent in some area. If you can fulfill one of these twoconditions, you are welcome to go to these countries.
At last, good luck to you.
