Does the insurance for a Non-OA visa have to be valid at the time of application, or can it start later?

The conversation revolves around the requirements for applying for a Non-OA visa in Thailand, particularly concerning the insurance policy needed for the application. Several comments indicate that while the insurance needs to be valid, there is flexibility in its start date. Users suggest that purchasing insurance to begin on the date of entry is generally acceptable, provided it meets the embassy's compliance standards. It's emphasized that the insurance must cover the duration of the stay to avoid any delays or issues upon entry into Thailand.
