How can I go to America without a passport from China?

You can not do this legally without a passport:

• Try to get political asylum at an American embassy or consul and hope for the best.
• If you can get into a country with high refugee emigration such as in North Africa and join the crowd, you may get into a country that will accept you as an immigrant, possibly the U.S.
• If you can get to Mexico, you might be able to pay to be smuggled into the U.S.
