Apply for B2 visa, and provide proof of appointment and medical expenses of American hospitals.
The specific process is to translate your own case into English, and then use the translated case data to make an appointment with an American hospital. After the general appointment, the hospital will let the domestic patients pay the advance payment, and then after the payment, the hospital will send an invitation letter to the patients, and then apply for a medical visa with the invitation letter and the recommendation certificate of the domestic doctors. Last time, we also wanted to go to Anderson, consulted Hangzhou Wuzhou Hospital, and finally let them do it for them. I am afraid that if I make a mistake, I will delay seeing a doctor. For specific steps, please ask Hangzhou Wuzhou Hospital. They have information. Our last advance payment from Anderson was $24,500, and the invitation letter was also translated by Hangzhou Wuzhou.
