Hello, I am a French passport holder and will be returning to Thailand with a Visa O over 50 retirement visa at the end of May. I understand that the French embassy provides an income verification letter. However, when I present this income verification document to Bangkok immigration when requesting the one year extension, can the immigration officer choose not to accept it? (I understand that everything about our lives in Thailand is at the discretion of Thai immigration and I also am aware that I can transfer 800,000 baht into a Thai bank account and present this as financial proof instead.) I am asking for clarification from anyone who has used the income verification method and if it is feasible or risky option. Thank you.
