What does it mean when my visa status changes from pending documents checked to processing pending approval?

The change in visa status from 'pending documents checked' to 'processing pending approval' indicates that your application has passed the initial review and is now under consideration for final approval. This usually involves a more senior official reviewing your application, who will decide whether to approve, reject, or request additional information. It is generally seen as a positive step in the application process, but there are no guarantees until the final approval status is granted.
