Can Shanghai residence permit and social security be renewed after 3 months of suspension?

Your processing time is similar to mine. To answer your first question, if you can successfully renew your residence permit, the social security society that will be handed in later will merge with the previous one. In fact, social security is like a bank card, but for you, the company you pay has changed. On the second question, I have carefully studied official website's statement-21century talents online, apply for residence permit. The renewal fee is just like a new one when it expires, and it will be even more troublesome if it is missed.
