it's a big job... Took us ours/days to gather all the documents. She had to dig up quite a few. 'Just' for a holiday.
And then the costs: my local council in the Netherlands, VFS Global, the visa itself, the trip to Bangkok from her home town. All together the likes of 200 euro... She did not have a passport. So we had to get a new one.
But at least the European countries openly admit they don't trust the Thai partners... In the meantime the EU is flooded by, so called, refugees (getting all kinds of benefits)...
I understand. Because, to get into the Schengen area, as a Thai, you need a very expensive visa and a pile of documents. (Not that the average Thai can afford that).
It pisses them off (and me too, because of course I paid for it this year for my GF)...
Secondly, there are Farang out there 'using' the system. They know that. The officers are getting more alert.
And lastly. It does not matter what the rules are and how many runs you have done. It all depends on the attitude of the officer...
