Can I extend my Non Imm O 90-day visa for 30 days in Thailand?

The user inquired about extending their single entry Non Imm O visa for an additional 30 days before its expiration on October 15. However, responses indicated that a 30-day extension is not available for Non-O visas. Instead, they can apply for a 1-year extension based on their visa's original reasoning or a 60-day extension if they have Thai family. It is advised to apply before the visa expiration, and specific requirements for the extension were mentioned.
