There is no amount of time out of the country that will make any difference, as your history is on the computer. Anyone who tells you otherwise is delusional.
No there is not. History is history and can't be undone with time out of the country as it is all computerised now at the airport. You will need to look at other options. Get a job with WP, business visa or Elite visa or get married (if that is an option). Good luck.
Not sure how many start up entrepreneurs will be making 200k a month too quickly ;) For the I visa, you need to invest 20 million baht, damn that is a lot......I guess these are all just steps towards a higher quality of expat in Thailand with money and insurance. Fair enough too..............Great visa options though. No work permit.
6 month multi entry tourist or 60 days tourists, but not a good long term strategy. Or send 800k to a bank in Thailand and leave it there. Get a 90 day NON O and then enter Thailand. Extend for a year and get a multi re-entry permit. Come and go when you want. Extend every year while in Thailand.
