understood, it's just that my wife and I both British had a problem renewing our retirement visas this year. For 15 years Jomtien Immigration accepted a copy of our Certificate but this year refused and told us to get it stamped in Bkk at Thai Consul. We went to Bkk and they declined to stamp it saying it need to go to UK for an Apostile stamp. After we got the stamp from UK Bkk again declined saying it had to be stamped by Thai Embassy in London ! We did all of the above and after nearly 3 months finally got it sorted !
