Can I be the Devils Advocate - Yes ,I get frustrated doing the 90 days run but we are suffering because of the few who flout the law . I only wish the UK government were more forceful in applying their immigration laws . For the majority of us it only represents less than half a day in an otherwise 90 days of not doing very much .
Yes, you may be the Devil's Advocate but I am afraid I do not see the connection between a 90-day report and those that flout the law. If one flouts the law then presumably one does not bother with the 90-day report nor the need for any kind of visa or visa extension at all. They come into the Kingdom on a 30-day visa exempt stamp, fly low, stay below the radar and only surface when they have to leave - penalty a 20,000 Baht over-stay fine. I do not see that a 90-day report contributes anything to anyone. It certainly does not deter anyone who flouts the law, in fact, it may even work in reverse. It may actually encourage people to flout the law and accept that one day it will cost them 20,000 Baht.
Actual cost to stay legal per year:
4 runs to file the 90-day report - say 2,000 Baht in transportation expenses
1 visa extension each year:
1,900 Baht for visa extension
2,500 Baht for letter of income from British Embassy
500 Baht transportation expenses
500 baht for tea and biscuits in M&D
Total cost per year: Approximately 7,500 Baht per year.
If you stay below the radar, flout the law, you would break even on your 20,000 Baht penalty/fine within 3 years.
I my own case I have been here 10 years and had I flouted the law I would be better off to the tune of some 40,000 Baht plus. And I may add, I have never been stopped and asked to show my 90-day report or my visa extension. So, I ask the question again, what purpose does a 90-day report fulfill? It doesn't even top up the tea fund - its a free report!
