What is the procedure for submitting documents for a Thai O-A visa application online and do I need to wait for confirmation before sending my passport to the embassy?

When applying for a 1-year Thai O-A visa online, it's advisable to upload un-notarized original documents during the application process. After submitting your application, you should receive an immediate email confirmation indicating which documents must be submitted in person or by post. If you're mailing your passport, it's generally best to wait for this confirmation, as it might specify additional requirements. However, based on experiences shared by others, if you are submitting original documents in person to the embassy, notarisation may not be necessary. It's essential to check the specific requirements with the embassy directly to avoid any issues.
