Extended data:

Under normal circumstances, the state will not issue visas to the following people: patients with infectious diseases, mental patients, drug addicts, drug traffickers, prostitutes, deported people, people who endanger national security and social order, terrorists, people who defraud visas by false testimony, and people whose living expenses are not guaranteed.

If the applicant's first visa application belongs to a certain country (region) and is rejected according to law, the applicant does not need to apply for a second visa. ?

If the reasons for the first refusal are documents and other aspects, complete documents should be prepared before the application, or the application should be made at the time agreed by the embassy or consulate officials.

It is particularly noteworthy that we must strive for the second approval. Otherwise, the possibility of winning the bid for the third time is even smaller. So the preparation for the first visa will be very important.
