What is the best visa option for a 4-month stay in Thailand?

For a 4-month stay in Thailand, the most common suggestion is to obtain a Tourist Visa (TR) for 60 days, which can be extended for an additional 30 days at immigration for a fee of 1900 baht. Alternatively, a strategy involving visa exemption for 45 days followed by an extension of 30 days can be employed, allowing for border bouncing (exiting and re-entering Thailand) to maximize the stay, potentially totaling 150 days. Another option discussed is to obtain an E-Visa for 60 days, extend it for another 30 days, and then execute a visa run to gain additional stay time.
