Can I extend my 60-day tourist visa at Jomtien immigration two weeks after arriving in Thailand?

The user is inquiring about extending their 60-day tourist visa at the Jomtien immigration office two weeks after arrival. Responses indicate that Jomtien immigration only allows extensions during the last week of the visa validity period, while another commenter noted that the Bangkok immigration office allows for extensions up to 45 days before expiry. Experiences shared reveal unpredictability at the Pattaya office, with some suggesting using an agent if unable to extend directly.
