What does the Under Consideration stamp from Jomtien immigration indicate about my 60-day COVID extension?

The Under Consideration stamp you've received from Jomtien immigration indicates that you are required to return on April 5th to finalize your COVID-19 60-day visa extension. On that date, you will need to present your passport, after which you will receive a receipt and be instructed to come back the following day to collect your passport with the full 60-day extension entered.
