With the exchange rate being really bad at the moment I don't want to exchange £19,000 into Thai Bhat so I have the 800,000 for the retirement visa. I understand if I get a visa agent they can get me the visa without me needing the 800K. If I fly in on 30 day visa exempt, will this be enough time for the agent to get the retirement visa for me. I would be meeting the visa agent on the 2nd day after arriving, wont be leaving until the 3rd week.
