visa for new born if my husband and I both have Chinese visa

Since your child is born in China, it has Chinese nationality automatically. The process is complex to get it a permit to stay in China.

You are suggested to consult your local PSB for consulting. Personally speaking, you need to go to the PSB to give up Chinese nationality. You also need to contact your country's embassy in China to have a passport for your baby. Then you can go to the local PSB to apply for a exit permit to leave the country. After leave China mainland, the baby can try to apply for a S type1 to live for a long time in China.
