"Businessmen have also voiced their concerns, claiming that business trips will become more difficult to organize, and pointing out that secondments which are commonplace here will no longer be as easily organized."
are these "businessmen" for real?? That's why visa on arrival was canceled in the first place: it was a massive abuse of these tourists visa on arrival, as they were used instead of Business visas... do these "businessmen" understand what they are complaining about?
Company can NOT use the tourist visa on arrival for secondment or "visa-run" for their temporary employees, or consultants!that's way it was canceled, because of these irresponsible companies who used to abuse this rule.
