This is a info post based on my experience today at Chon Buri Immigration . I went to apply for a 1 year extension to my Non Immigrant O visa based on marriage to a Thai National. 2-3 weeks ago I visited Chon Buri Immigration and collected the check list required to apply. This is not my first extension so I knew what was required but wanted to make sure that I had the 'up to date' check list. Upon arriving at counter 6 the Immigration officer started to check the documents and was rejected because you now need proof that your marriage is still current and the last 3 months worth of bank statements that you have the seasoned funds in. These 2 extra requirements are not on the check list and if they had of been I would have complied. We were told to come back at 1300 tomorrow. We then went to the local Amphur and obtained the documents showing our marriage was still current and my wife said the lady there said that many people had been that day requiring the same document. Now before any one asks I had the letter from the bank and I deposited 100 baht to my account and done a bank book update this morning and had photocopied the bank book showing the funds being in there for over 3 months. I will update the bank book before I go again tomorrow and have printed out from online banking my last 3 months worth of statements. I hope this helps anyone applying for a 1 year extension based on NI O Visa based on marriage and if anyone else can concurr they have had a similar experience at Chon Buri Immigration the drop a comment. Cheers.
