Is there anyone who has experience with Beijing Visa Office application lately?

[liherb]

For those who choose Beijing as Visa Office, there are some specific requirements that are different from other visa offices.
1) "Federal Skilled Worker applicants and their accompanying spouses are required
to apply for verification of the highest post-secondary degree/diploma obtained in
China with the China Academic Degree and Graduate Education
Development Centre(CADGEDC)."
2) Household registration (hukou)


Is there anyone who has dealt with these two tasks? Especially for problem 1), what is China Academic Degree and Graduate Education Development Centre and how to deal with them? I've been out of China for years and really don't know of it.
For problem 2), should I submit original hukou or just a translated/notarized photocopy of it?

Thanks a lot.
