maybe in person? But many embassies are using the Thai e-Visa. Submit documents, pay the application fee, then they review and may request further documents . It's non-refundable. It's not a deposit. Many have been rejected for trivial reasons and minor errors (name spelt wrong after auto import after passport photo upload, incorrect passport expiry date, etc.) and have to pay again if they want to re-apply.
