Can you use proof of 40k baht monthly income instead of 400k baht for a Non-O marriage visa in Thailand?

The requirement to show proof of 40k baht monthly income instead of 400k baht for a NON-O marriage visa can vary depending on the local immigration office. There are recent observations that some offices are not accepting this method unless the applicant is legally employed in Thailand making at least 40k per month. It's advised to confirm specific requirements with the local immigration office regarding income proof for a yearly extension.
