Apply for an American visa? My mother's friend invited her to stay in America. How can I get a visa easily? Are you visiting relatives or friends or traveling by yourself?

Don't visit relatives and friends. It must be hard for you to immigrate. It would be better to have a Malaysian visa. But when you go together, you must bring many photos of your relatives and friends in China to prove that you have a family in China and it is impossible to immigrate to the United States.

Nothing else. You should go to your mother's friend's address and get your proof of funds. With your friend's address, if anything happens to you, you will find your mother's friend.
