Can I extend my tourist visa in Thailand one month before it expires?

A user inquired about extending their tourist visa one month before expiration. Responses indicated that it is generally allowed to extend a tourist visa up to 30 days before expiration, but experiences vary by immigration office. Several users advised going during mid-week to avoid long wait times, with some stating that certain offices, like Jomtien, may restrict extensions until closer to the expiration date (within a week). The conversation also touched upon the nuances of extending visa statuses and different rules applied by various immigration offices.
