How long can I get a visa after a face-to-face visa in Mexico?

If the interview is successful, he will ask you to pay, and the visa will be issued in a few days. A friend tried it for about ten days. There are cheaper hotels in Shanghai, and it won't be too expensive for ten days. Generally, you can call or ask about the appointment time after receiving the approval. Sometimes there are many people, and they will wait for a month or two. Don't worry.
