Can I just submit the diploma ? Or do also need my transcripts?
I'm so confused about this.
I'm still doing my Phd and I'm planning to submit my master's degree from China.
Get any evidence you have. The more the better. Btw, if you're MA/MS is from China, you need to get the degree evaluated to prove that it's the same as a Master's in the U.S. Have you done that already?
