More qualified & smart people should work at the immigration. Most of them do not know about transit visas, tourist visas and rules followed by other major countries. I always find them asking to their so called seniors, for advise. The parking area has become a taxi stand for the unmarked microbuses. There should be specific number of airport taxis and no authorized help person at the arrival hall otherwise the re-entry is horrible. This country will take long time to rise if the airport is not found friendly and comfortable by the foreign visitors/investors.
