The school has a summer camp to the United States, and I can stay in new york for 2 1 day. Can I hide there and work secretly and never come back?

This is impossible, because Xia Lieying's passport is short-term, and it is illegal to stay in China after the time limit. If found, they will be sent back to China.

Of course, if you have to be an illegal household, you can't break into houses in America, so you can find a house in America and stay indoors until the end of time.

If you want to go to school in the United States, it is inevitable that it is better to go to American schools through formal channels in China, and black households have no other choice; But it seems to me that you want to work there. If you just go to work in the United States, you can find an intermediary to apply for a study visa, a tourist visa or a business visa directly, so that you can work in the United States.
