I plan on coming to Thailand next Yr but want to stay as long as possible which visa Is best for this I was thinking maybe education visa learning Thai language what is the criteria for this & what proofs need to be shown ie proof of money in account etc & how long does the visa last
TLDR : Answer Summary
For long-term stays in Thailand, the Non-Immigrant ED visa is a viable option, allowing for a stay of 90 days and is extendable by attending language classes at a recognized institution. The visa initially requires enrollment with proof (documents from the school). While generally no financial proof is needed, it can vary by consulate. The METV (Multi-Entry Tourist Visa) is also suggested as it allows for up to 9 months of stay in increments, providing more time to transition into the ED visa.
