This is a new one to me:
15 Dec 2017 applied for Extension of Stay based on marriage. Handed over all the needed copies and got the 1 month under consideration stamp till 7 Feb 2018.
18:35 tonight a phone call from an Immigration Officer working for Krabi Immigration, we do not have copy of your passport and visa and Extensions from the last years, can you please send by line to us.
I just send all pages, ID page, Visa Page, entry stamp, TM6, Extension of Stay till 2016, 2017 and under consideration till 7 Feb 2018.
It is Friday night, Immigration is closed, as well as tomorrow and after tomorrow. So 5 Feb is the first day to contact them, it will be a close call if they need copies again.
I asked if I have to come with new copies on Monday but no answer.
