Australian employer-sponsored green card has been nominated. Why hasn't the immigration office come down yet?

The Australian employer-sponsored green card has been nominated, but the application materials are still under review. The employer has submitted a green card application to the Immigration Bureau and has been nominated. The application will enter the review stage. At this stage, the Immigration Bureau will review the application materials, confirm that all the requirements of the green card application are met, and verify personal information and employer information. This process will take some time, depending on the application and the workload of the immigration office.
