Just go ahead and try. Tell yo

u the truth, the chinese embassy is so messy. they don't really look your application. For your safety, just register first and send the application later.
I have a friend that she's a NIH funded Post-doc. She's not supposed to file the waiver through Chinese embassy.
She went ahead did it. It was done.
Good luck! The more time you get, the better. My personal opinion.
