Is it better to apply for a long-term visa for Thailand in my home country or in Thailand?

When considering whether to obtain a long-term visa for Thailand in your home country or upon arrival in Thailand, it's generally advisable to do it in your home country. This approach can save you time and effort, preventing the need for multiple trips to immigration offices in Thailand. Additionally, if you don't have a Thai bank account yet, you will need the visa to open one upon arriving in Thailand.
