What documents are required to confirm legal residence when applying for a Thai tourist visa from France?

Driving license or utility bill

Submit you France drivers license. Done.

I uploaded a copy of the property taxes as proof, it was accepted

>7 . Confirmation of legal residence in a country in which you are applying for the visa

For people who are in a foreign country already, they need proof of legal residency (i.e. for people who are from Mexico but currently in the USA, they want a Green Card).

IF you are in the country of passport, upload another copy of your data page.

Question 11 takes countries that have more than one embassy/consulate into consideration. If you're in a country with only one, you just need to attach your passport again. If you're in a country with multiple, you need to attach something that proves where you live so that they can verify you're sending it to the right place (for example: the U.S. has five consulates; someone in California should be sending their app to the LA consulate, not the D.C.; this person would prove they're sending it to the correct place (LA), by attaching something like their ID or bank statement that shows their Californian address).

Just upload a copy of your passport if you are residing in the country of your passport. If not upload a visa that shows you have legal residence to be there.
