According to the guidelines, when can a renewal be submitted before it expires?

A renewal can be submitted up to 6 months before the expiration date, which allows for ample time to process the renewal without any interruption of service. This extended period is beneficial in ensuring that individuals or entities can maintain their status or licenses without the risk of a lapse while waiting for the renewal process to be completed. Submitting a renewal well in advance provides time to address any potential issues that may arise during the review process, thus enhancing overall efficiency and compliance with guidelines.

The other options suggest shorter timeframes that do not align with the established guidelines for timely renewal submission.
