Do you need a medical examination to travel to the United States?

Generally speaking, American tourist visas do not require a medical examination. Of course, if you are old and the embassy asks for a medical certificate, just say so.

For American tourist visas, you need to make an appointment for a face-to-face interview 1-3 months in advance, and then fill out the embassy form online and submit it to the embassy to prepare relevant face-to-face materials. Then it's time for an interview. Face-to-face interviews usually ask 4-5 questions, so you should know them carefully, or you will be rejected. At that time, the interview told the result that if you get a visa within 3 working days after success, you will be refused a visa letter. There is another situation, that is, administrative reconsideration, so wait.
