Q1 type renewal

Sunny, you should extend it one month earlier before it expires, so you cannot do it now. You need to prepare those documents first including your passport, the application form affixed with a recently-taken passport-style photo, medical report, valid registration form of temporary residence, an invitation letter from your husband and copy of his Chinese ID card, and your marriage certificate. And then submit the application to the exit and entry administration of the local PSB to extend it.
