Can a French citizen without residency apply for a 60-day visa on arrival in Thailand and what are the best visa options for a 6-month stay?

fwiw, I've read that you don't need proof of residency for DTV but just proof that you are staying in the country from which you apply -- ie, a hotel booking

The visa exempt is free as

also tells, but when you want to stay about 6 months, you can extend the 60 days with 30 days once and that will cost you 1900 baht plus some extra for copies and pictures.

Then you have to leave the country before stay any longer. What this will cost depends on the way you organize this.

Then you will get 60 days free entry again if everything goes as planned an can extend again for 30 days paying 1900 baht.

The DTV is baht, but it will cost you quite a bitmore because Thai embassies have their own exchange rate. 😡

Two times 1900 baht is cheaper than cost of DTV, it should also be possible to add the cost of borderrun and still stay below the cost of DTV, but DTV is valid 5 years so if you possible visit Thailand again it might be a better idea to go for DTV.
