What should I do to go to Kazakhstan?

Do you know anyone in Kazakhstan? If yes, please ask the people there to send you a letter (note: it must be Kazakh, and the letter must be sent by the post office, including an invitation to visit relatives there). You can't open the envelope by yourself when you arrive. Take this letter to the public security bureau where your account is located. People in the police will ask you about the relationship between the other person and you, the name and address of the other person. So, after the channel, contact the person who sent you the letter and ask the previous questions clearly. If your answer is the same as that in the letter. When the time comes, the people in the public security bureau's accreditation office will tell you how to go next!
