Sadly you're a little deluded. You think Thai immigration is going to send emails whilst you're trying to enter the country? Hey, it's all good! I guess I'm a little more streetwise in Thailand. 20 years ago I bought a driver's licence in KSR at the same time I bought my university degree from the same dodgy forger so I could become a teacher!
Wow! Most countries of the world a business card means sweet nothing. You realise you can get these printed anywhere? I don't think Thais would fall for that one!
