Hope someone can point me in the right direction.
I am currently on a long stay o-a visa multiple entry obtained in London. I was residing in Hua Hin and did my 90 day report on the 28/11/18 . I have just arrived back in the uk for Xmas and will be returning to Thailand on the 8th Jan and I will be staying permanently in Pattaya. On my arrival can someone tell me when Am I required to inform immigration ? and what documentation I need .
Many thanks
