What should I pay attention to when applying for a visa?

General visas can be obtained on the same day or the next day. It is normal if vo only provides the receipt during the interview. In this case, you need to call the visa office a few days before the date marked on the receipt, and you can usually get it one or two days in advance. When you get a visa, you must check it on the spot. Sometimes the visa office will write wrong information (I have encountered it twice myself), which will have an impact on entry and exit. Being asked for supplementary materials: This situation is not a refusal, but the visa officer thinks that your materials are insufficient and they need more information to decide whether to grant you a visa. You only need to prepare supplementary materials according to the requirements of the visa officer, which is why I object to false materials. Supplementary materials are often loopholes, and the more you fill them, the bigger the loopholes.
