Jeff LeBlanc Apply for a "O" Non Immigrant visa at the Thai Embassy in your country. It will be good for 3 months. Then enter Thailand and open a Thai bank account, which you will get with this type of visa. Transfer 800,000 THB to this account. After it's in your account for at least 2 months, you can apply for the 1 year retirement visa. So put the money in the account as soon as you arrive in Thailand.
I used an agent in Bangkok who collected all the necessary documents from me. It cost me 250 USD but it was worth it. An employee of the agent accompanied me to the immigration in Bangkok, and he could use the fast track. No long waiting time. I got my first retirement visa within 1 hour.
