Correct me where I am wrong. But an experienced AGENT in Thailand will have history of how DUI's have been approved/not approved for specific situations, as the agent has seen several applications. They would be able to look at the client's complete application package and be able to give some good advice or guidance about how to proceed. Example they might say "DTV may not be the best way for your circumstance, you may have to go with the Thailand Privilege Visa. What I have learned in my few business dealings in the Kingdom is that typically if you work with a reputable and influential Thai person to handle your business... it's amazing what you can get done.
