If you want to go to America now, you must go through American formalities! But not immigrants!

How long will you stay in America? In this case, you can sign a tourist visa yourself, but I suggest you find an agent like CITIC, who can help you fill out the form. All visas require proof of assets, and the more the better. After that, it is valid for one year, and you can stay for half a year each time. If it takes half a year, you can go abroad (Canada or Mexico, as long as you leave the country) and then enter the country, so you can stay until the visa is valid. If you want to renew your visa after it expires, you must go back to China to apply for a new one, or apply for a work visa here, otherwise you are illegal immigrants. ..
