What does the "under consideration" stamp mean when extending a tourist visa in Thailand?

The "under consideration" stamp indicates that the immigration office is reviewing your request to extend your tourist visa from 30 to 60 days. The decision will depend on the reasoning you provided, and it may include scrutiny of your circumstances, particularly in relation to the COVID-19 pandemic. Comments suggest that you should return on the specified date for the outcome, and be aware of the implications if your extension is denied.
