Hi, I am from Indonesia and I have accepted to work in Macao. How do I apply for the blue card (work visa)? How long will it take? Thank you.

You should apply through Chinese embassy or consulate in your place, For the purpose of work, following documents are required:
1. A completed application form; [Note: The application form is available at the respective Subdivision and the website of the Public Security Police Force.]
2. Copy of the bio data page of a valid passport/travel document;
3. Copy of employment approval document issued by the Macao authorities (i.e. the application or renewal application of "Authorization to Stay for Non-resident Workers" which has been verified by the Macao Immigration Department). [Note: The original of this document is not required.]
Processing time takes about one month because it should be approved by Macao Immigration.
