in your first answer you said incorrect to the statement that an onward travel ticket is necessary and your "proof" was that you were not asked . That was what I answered to. And incorrect it was not because some airlines require it. I see you have modified your opinion after this.
you have proved nothing only because it worked for you. Prove of onward travel is required by a number of airlines. I have been asked by SAS KLM Thai Airways - not every time but they do ask
I have to comment on this again. It is so strange. I was supposed to leave Thailand sep 1 which is 3 months after my arrival. The officer stamped under consideration and I must return October 1! This I consider overstay 1 month. I discovered it late at home yesterday and wrote to them on Line saying I would be overstaying and shouldn't it be sep 1 I should get my visa. The answer today was OCT 1 and it seems I will not be overstaying since he referred to the stamp. Ever heard of this???​
you guess wrong - no change visa type. You apparently think I don't know what I am doing. I am here on a non-o based on marriage and I want permission to stay 1 year and that's what I applied for. 1st document was tm7
no it doesn't mean he just filed his 90 days report. Certificate of residence (if that's the same as proof of residence) can have different purposes - you can get it for opening a bank account - you can get it for getting a drivers license etc etc. The purpose is mentioned in the certificate. I opened a bank account in Krungsri about a year ago with that and I just got one for a drivers license
