Strange situation, is this correct? Have a non OA multiple entry, made in Holland 2 Feb 2017. Entered Thailand on 8 Mar 2017, and got the stamp from immi "until 7 Mar 2018". So far so good. Went on 18 jan 2018 for a break to Vietnam, and came back on Jan 21, 2018. Got a non OA stamp with "until 20/1/2019" so far so good.... Now last Tuesday 2 Oct 2018 go for small break to Holland and came back today. Immi did only stamp "until 5 Nov 2018" so 30 days instead of till end of the Non OA, which is 20 Jan 2019. The Non OA was a multiple entry type so if stamped before till 20 Jan 2019, it should be ok till that date? Immigration officer says No, now not good anymore. Is this a mistake or?
