Hello everyone, I submitted my application in Hanoi on the 18th and provided additional documents on the 19th. Today, my application was rejected. However, I do not know the reason for the rejection.
I applied under the soft power category (Muay Thai), and the gym I chose is properly qualified. My bank account also has sufficient funds.
What should I do next?
(Could it be related to the fact that I previously applied for two ED (education) language visas? Or is it because I hold a Chinese passport?)
