Is a joint bank account with my spouse acceptable as proof of funds for the Non-O Guardian visa extension in Thailand?

The general advice when applying for the Non-O Guardian visa extension is that proof of funds should ideally be in an account entirely under your name. While some immigration offices might accept a joint account, it is often required to show double the necessary amount since only half of the funds are considered yours. Therefore, if using a joint account, be prepared to possibly show more than the standard requirement. It's highly recommended to check the specific requirements with your local immigration office before applying.
