Final answer:
The latest day to submit the license renewal form depends on the specific regulations of the licensing authority, typically before the expiration date.
Step-by-step explanation:
The latest day of the expiration month that the license renewal form should be submitted will depend on the specific regulations of the licensing authority. In most cases, it is necessary to submit the renewal form before the license expiration date. For example, if a license expires at the end of February, the renewal form may need to be submitted at least a month prior, or by the end of January.
