How long does it take to apply for an American visa in advance? I already have a passport. Ask experts for answers! The sooner the better!

Personal advice is best two months in advance. Because there are two parts to waiting, one is the time to wait for an interview, and the waiting time is different at different times of the year. If you make an appointment now, the embassy usually has to wait a month to make an appointment, but when I made an appointment in April this year, I only waited a week; In addition, after the interview is completed, if it is passed, it may continue to be reviewed, which is commonly known as check. Whether it will be censored varies from person to person, depending on your personal situation. For example, if you work in a sensitive unit considered by the United States, or if your major is sensitive, you are likely to be investigated. If it's check, it takes about five days for ordinary people to get a visa after passing the face-to-face visa, while it takes at least three weeks for you, and some even longer. The longest I have ever seen is only two months. So I suggest you apply two months in advance, which is safest.

Tourist visas can be handled at all embassies in the country, not necessarily at the embassy near the residence. But if you apply for it for the first time, you must sign it yourself. The visa officer will ask you some questions.
