The embassy of Thailand in France is pretty useless when it comes to getting a tourist visa.
I requested one for me, my husband and our 2 kids more than a month before we leave. We prove everything requested (money, utilities bills etc).
1 day before we leave France, we get a request for more information (mariage certificate, even though our married names are on the passports, birth certificates for the kids) with the comment that we should move our trip by a week or so, as they now need more time and they will not issue the visa once we left France (we do for 2 weeks in the UAE, so would have been plenty of time).
Of course I am not postponing my trip and paying another 4k euro or so.
Simply means I have wasted 140 euro and still need to find a way to extend while we are in Koh Lanta.
Especially annoying as my friend who went through the same in the Netherlands didn't have any of this and got it sorted in 2 weeks.
