You have to do one year using 800k in the bank and during that year make the 65k/month deposits ready for the subsequent extension. You can of course spend the 65k each month. I believe @DrJack54 is doing this.
Of course I have, but only on the way to or from somewhere else, no compelling reason to hang around there. Elsewhere the trikes seem to operate well enough.
Me too, many times. Those planes were bad and had that nasty flat but not horizontal business class seat that you slid down the whole flight. Going was bearable, returning dreadful. Things will be better this time round I'm sure.
It is a joke but even then they can't do it. I had to do the driving test last year. I was the only non-Thai in a group of about 20. I passed, along with only 4 others. The remainder had to return on another day and retake only the specific driving manoeuvre they failed. No actual road driving at all, I doubt some of the group had ever driven a car before the test.
On a recent entry I deliberately didn't have a printout or show my phone to the IO, just handed over my passport. I wanted to test the system. No issues at all. And consider those who are sent away to the terminals to complete the TDAC, they also return to the desks without printouts and quite probably nothing on their phones either. It is certain that if you have completed the TDAC as required and arrived on the day you said you would all the information is on the system already.
It's an arrival card, nothing more, nothing less. Airlines never used to ask to see your arrival card in the past, and if they do now they are wrong. No need to pander to their paranoia.
You have to be in the country you are applying from. So to apply from Germany you would have to go there. You can apply in Nigeria, should be the same process but nothing can be guaranteed, why not just try?, there's nothing to lose.
You will have to leave and re-enter at least once to get the 6 months you want. You can enter visa exempt or tourist visa but you'll still have to extend in country and leave once. But it's easy enough to do.
For a "retirement" visa you don't have to be retired, only have to be over 50. But that in any case would only give you 90 days so probably not what you want for this trip.
The point I was making is that phone (not data) roaming costs nothing to receive SMS messages. You can enable that without having to buy a package of any sort. If you answer incoming calls you'll be charged, so don't.
