I have a non immigrant O visa, married to Thai national, was giving 3 months and told to go back today with all the correct documents to extend to one year, took everything they had on there list, wife's documents,money in bank, they then sprung on me I needed a letter from apartment manager, and also a copy of her Thai identity card, this seemed ludicrous to think if I couldn't obtain an extension because someone would not part with there identity card, fortunately for me she did and I trailed back, so there is nothing on the list of what you require that mentions this, in English or in Thai, so I made an extra 60km journey on the whim of some official, no wonder people get disulisoned with the Thai system, it's a joke. So anyway just a heads up for anyone in the same boat.

I had to have THREE copies of every page of my passport from cover to cover (last Thursday)......

In my experience, the immigration officials will always want one more paper than you present, its a kind of a power thing, maybe they want you to know that they are in charge.

I always present the reasonable minimum number of documents, then when they ask for document xx or yy, you produce it and they then ask you to then photocopy it.

However despite rationing papers in this way, they will sometimes still manage on some years to come up with some document one hasn't ever brought before.

Look on it as a game of chess, the important thing is to win (get the extension).

it's all part of life in Asia, don't get disillusioned by it and don't take it personally.

They even phoned me to produce my Decree Nisi from my UK divorce years back . I said why, I could not marry in LOS without showing all that stuff years ago......... Why the problem. Actually I could not find it so a bit in limbo. More to the story but..............

Proof of residence appears on many lists of needed documents if you are not living where you wife's house book is for.

A rental agreement with copies of the owners house book and ID attached is normally what is required to meet the requirement at many offices.

It might be required but it would help if it was on a list of required documents,had original and copies of rental agreement, but wouldn't think I would need a copy of apartment managers id and letter from her confirming we live there,think immigration want us to be mind readers, unnessary waste of my time and morning
