Hi, today I went to Immigration Div 1 to renew extension of stay on Non Imm O (Thai wife) visa.

Some feedback, I had everything they required however Immigration wanted 2 copies each of the following: map of residence, photos of my wife and I, Passport personal information page, Kor2 and Marriage certificate.

I had one copy of everything plus originals but was surprised when a second copy was requested. Quality of the copies I had was fine. Everything was then accepted and I now have the 'under consideration' stamp.

So I suggest you have 2 copies of everything to be on the safe side.
