attaching my visa to my husband

Dear, you can just go to the exit and entry administration of the local PSB to change your current residence permit for work to a new residence permit for family visit.
The required documents include the application form attached with a recently-taken passport-style color photo, your passport and copy of its data page, the temporary accommodation registration certificate, an invitation letter from your husband, the passport and residence permit of your husband (copy), your marriage certificate (original and copy).
