Can I extend my 2-month tourist visa in Thailand a month early?

The poster is currently on a 2-month tourist visa in Thailand and wishes to extend it for another month while they still have four weeks left. They are inquiring if they can complete the extension process at the Immigration office now, or if it would be considered too early. Comments from the community suggest that while most immigration offices allow extensions 30 to 45 days in advance, some may require you to wait until closer to the expiration date. There are options for a tourism extension or a Covid extension, but eligibility may vary based on nationality.
