Under normal circumstances, no matter which country's international students fail in the course or thesis, they can't apply for certification directly in the detention center. In addition, don't say that you didn't get a degree, even if you successfully got a degree, if you can't do certification in some cases, such as you can't provide a complete original, there are unrecognized transfer credits on your transcript, or your domestic undergraduate experience is flawed. And the detention center will also examine the continuity and cohesion of all stages of your overall study experience during your study abroad. It will also check your length of stay in the UK and your visa type. Moreover, your teaching methods, teaching time limit, awarding standards and evaluation methods in foreign universities are also subject to inspection by detention centers. It doesn't seem easy to apply for academic degree certification in your situation.
