When should I return to immigration for my covid amnesty stamp and how long will it last?

A user canceled their extension of stay stamp due to a canceled work permit and applied for a 60-day COVID amnesty stamp, receiving a consideration stamp valid until November 23. They asked if they could return earlier on November 19 or 20, and if they would receive a stamp valid until November 30 or December 30. Responses indicated that they should return on the date specified in their passport (November 23) and that they would receive a 60-day extension based on the date they applied, likely valid until January 7.
