Q: What does the status "With editor" mean and how long does it take?

This stage indicates that your paper has not yet been sent for peer review. As per the normal journal processes, the editor first conducts an initial screening of the manuscript. If the manuscript passes this screening, it is sent for peer review.

The time taken for the different stages in the submission process varies across journals, but it is quite normal for the status to show “With editor” for over a month after initial submission. The reason why this stage can take time is that it is often difficult for the editor to find reviewers. The editor identifies suitable reviewers and sends out invitations to them, but on many occasions, the reviewers decline the invitations. If that is the case, the editor has to look for other reviewers.

I think you should wait for at least a month. If you still do not see any change in status, you can send a polite inquiry to the editor.
