My previous post was deleted before it was approved. That's ok. I will try again and cut to the chase.

My under consideration stamp, on extension based on marriage is cut short by a weekend, even though the correct day would be a monday, counting 30 days from my current stamp expires. That particular weekend I have to travel from Bangkok to north east, so can't make it to immigration before monday. Technically I guess it's not overstaying, but the stamp will be expired. My local immigration is okay with that, but could it potentially get me into trouble if stopped somewhere on the way home?
