yes...we are aware of that...and monitoring it.
We do expect it to be a REQUIREMENT FOR ALL O-A Extensions...and For Entry or Reentry into Thailand for O-A holders.
However as its so very new...its apparent that even Thai Immigration is still getting up to speed at entry points into Thailand. A mixed bag of reports. But that likely will become consistent in weeks and months ahead. Its best to be prepared with ones options when and if the requirement is fully monitored.
