Renewal of Work permit/Residence Permit.

The Hangzhou Municipal and Social Security Office mandated a Criminal Background Certificate for Foreign applicants to get the work permit. It was worded that people who needed this were people coming not the city and not necessarily for renewals. So last week, I went searching for their office to ask them.

Ended up getting pointed to to the Zhejiang Provincial Bureau of Foreign Affairs. I was told there that I did not need the certificate since I was already in country. Sort of my question is, will the PSB require the criminal certificate or will they just go on what is approved from the Zhejiang Provincial Bureau of Foreign Experts?

My assumption is that there are three hurdles in the renewal process,

1. Foreign Experts Bureau
2. Medical
3. PSB.

Is this still the case?
