You normally can enter without any problems because IO at the border normally not enforces these requirements, but according MFA requirements are still in place.
How can you know that I know zero while your previous contributions clearly show your knowledge about immigration is not very good, even below zero because you just post incorrect and wrong information. But why are you in this DTV group anyway? Since you are working in Thailand, you cannot have DTV.
knows a lot more than you about immigration or anything else. You always spread misinformation here. Overstaying certainly can be a reason to revoke a visa. Not likely they will do for a few days, but certainly possible.
When you do your first 90 day report on day 83 then your next will be at 173, which is before you have to leave. This second one can be done online, or prevented by doing the first not before day 90.
For a certificate of residence you need to go to an Immigration Office and you will need to have interaction with an immigration Officer to get that certificate.
So your remark that smart DTV holders never would go to immigration is just BS like almost all your remarks.
When that immigration officer looks into your info, it becomes clear you missed a TM47, and can decide to fine you with up to 2000 baht.
In case you behave the same at that office like you behave here, it will be almost certain you will get the maximum fine of 2000 baht.
A better advice than "check your dates" is just follow the advice MFA gives when you apply for the visa and just show your printed visa to the IO together with your passport.
Or did you also wait for the IO to request before you handed over your passport...
Maybe for a residence certificate to get a drivers licence? Or just because not everybody is so stubborn like you and not following the law and just do TM47 reporting like they should?
I know you try to tell stubborn and anarchistic people like you are smart, but the rest of the world just sees that as dumb.
Maybe YOU never go to Immigration, just speak for yourself, not for other DTV holders and OA holders, because many go to Immigration for all kind of reasons.
