Non O Based on Marriage Sa Keao immigration Arrayprathet. This might be of use for anyone looking to use Sa Keao immigration for their one year extension of stay based on marriage. It would appear that this office goes way beyond the norm to get this, I re-entered back in Jan on 30days visa free and went to apply for the Non O based on marriage with my 400k just transferred. This wasn't possible they said and they then laid out what I had to do. First I was to get another 30 days visa free, then I can get the 60 days based on thai family, and then I could apply for the Non O based on married and all this time I was to keep the 400k in my thai account. once I got the 3 month extension I also had to keep the money in my account and when I returned i was given another month extension for under consideration while my paperwork was sent to bkk. I had to submit the huge amount of documents to meet the criteria twice, once when applying for the 3 month extension and once when I went back to get the 1 month under consideration. I'm led to believe that this is supposed to be a 2/3 month process but for me, it's taken close to 8 months and yesterday I was finally given my one-year extension so such a relief, after all, we have been through. It must be said though that even though they have been very thorough they were extremely helpful at the immigration office and gave us clear and concise instructions each time we went and they were explaining it all really well. anyway, I thought this might be useful info for anyone using Sa Keao immigration as it appears to be a long process for some than at other offices so best to be prepared for that.
