Iam Indian working in Sweden on work permit a)can I apply for chinese work permit in sweden?

You can apply for China work visa in Sweden, your company branch in China should first get the Alien Employment License and Official Invitation Letter from a Foreign Affairs Office. Your husband and son don't need the Alien Employment License and Official Invitation Letter, they can also apply for China work visa as your dependents. The relationship certificate, such as birth certificate and marriage license should be provided.
