What is the approval process for a tourist visa extension in Thailand?

The approval process for a tourist visa extension at CW involves submitting documents and receiving an 'under consideration' stamp, indicating the application is pending approval. Community members report that this stamp typically leads to guaranteed approval, as they have successfully received their visa extensions within a week. One user clarified that the process has recently changed to a 7-day waiting period instead of 14, adding confidence to the outcome. It's also noted that the visa extension is specifically for visitors affected by COVID-19.
