Hi Rob and Tod
Did my first extension of stay based on marriage in Samui today
Your list of requirements posted recently was a huge help as there is a lot of paperwork
The only thing to comment on here is that they requested 2 complete sets of documents and an additional form STM 2 which they asked me to fill put and sign in duplicate
Kind regards
