Just a query, a Macau employer has applied a working visa for me to work there.

Hi!
I'm not sure though how long it would take for the processing? They have all my documents and they informed me that they submitted my records 4 days ago. Is there any online portal where I can check the status of the application? How long does it usually take to know the result? Is there a possibility of rejection?

Appreciate the help.
Many thanks!
