I went to Kanchanaburi immigration with all the correct paperwork to extend my non-imm o visa for marriage for 60 days. I was told that they would not process my extension without the presence of my wife, despite having originals and photocopies of all the marriage paperwork. So I had to go all the way back home, pick up my wife and make her sit in a crowded immigration office for an hour and a half, before handing over exactly the same documents. Is this standard practice? I got the original one year visa in Laos without the presence of my wife!
