Requirements vary by office, especially for custody, legitimation, home photos, and address evidence.
Thai Immigration generally requires photocopied documents (such as passport pages and certificates) to be signed before submission.

This checklist reflects the documents typically required; however, requirements vary by immigration office. Additional documents are often requested depending on individual circumstances, so please confirm the latest requirements with your local office. Final approval is at the discretion of the immigration officer.
