Hi, following maybe of help to some. I have a 12 month multi entry Non Imm O Visa based on Thai wife. Visa was obtained in Sydney and expires end Jan 2021 and allows me to stay in Thailand for 3 months before needing to bounce. My current stay ended 25 May 2020 and I have been on amnesty.
Today (and Friday last week) I went to Immigration office in Lak Si to apply for a 12 months extension. Today I was given an ‘Under consideration’ stamp and need to go back in 1 month.
Some feedback on my experience:
Immigration staff were very helpful and friendly however very strict on the Visa requirements. Need originals of everything you have copied. I had 400K in bank for 2 months and had Bank confirmation letter. Bank book needs to be updated on the day of attending immigration not the day before. I need to provide another update of Bank book (not letter from Bank) to ensure 400K still in bank on the day I return for under consideration result. Thai Wedding certificate + Kr.2 (this is provided with marriage certificate) was required. They did not accept just Thai Wedding Certificate. 4 photographs of wife and I in front of/in house including Room address number was required. Needed to complete and sign 3 additional forms acknowledging over stay penalty awareness. Cost was 1,900 Baht.
In summary very thorough and very strict however staff friendly and helpful. Make sure you have ALL your required documents.
