Urgent! Australian study visa

No, no, no. . If you apply for a visa in West Sydney, you will get a guarantee from West Sydney. In other words, in the records of the Immigration Bureau, your curriculum is a major item.

Unless you get the release letter from Xida University, you went to Kunming University. Think about it. Xida guarantees you that you didn't go. You didn't explain or release the letter. It means you didn't arrive at all. Xida University may report you to the Immigration Bureau, and your visa will be cancelled.
