(Jan to May 2022) and have some days left on your visa expiration stamp, please contact International Center and/or submit your "Visa Cancellation" request to this form https://form by May 10, 2022. So we can issue a visa cancellation letter for you before the end of May.
If you choose to leave Thailand before the end of May (May 31, 2022), that is fine. You can choose not to cancel because, by leaving Thailand, your visa will be automatically terminated. However, we recommend you properly cancel your visa.”
