@Alex *****
a good rule of thumb IS
find out how to register a thai married abroad at the local Amphur where you live,
compile all those documents from where ever they need to come from,
get them stamped certified, etc at where ever they need to be stamped from..
Make copies of all that stuff after it's stamped/certified too.
Go register the marriage, get the Kor Ror 22 and then you will know you have everything that a thai consulate could ask for.
