you can't get a multi entry 1-year Non-Imm-O Retirement Visa any more. You need to enter Thailand with a 90-days single entry Non-Imm-O Retirement visa, and apply for the "1-year extended stay permit based on retirement" (which many people wrongly call "retirement visa" but which is NOT a "visa" but a stay permit stamp in your passport). For this "one-year stay permit" you then can buy a multi re-entry permit for 3800 Baht. For both the visa application AND the application to the 1-year Extension, you need to fulfill the financial requirements (EITHER a minimum of 800,000 THB in your bank account, OR an affidavit of income from your embassy in Thailand over a minimum income of monthly 65,000 THB) For the application to the 90-days visa, you can use money on your home country bank account, or original income proofs, however for the application to the 1-year Extension on Immigration inside Thailand,you will need money in your Thai bank account or the legalized affidavit of income. If your embassy doesn't issue it any more, you need the deposit method for the first year extension
