one more thing,,,i heard if example from manila you flew to bangkok and from bangkok you will fly to qatar but you will not go outside the airport,, they said if example inside the airport you'll wait for your flight to qatar,,, is it true that you will not be required a visa.. actually i heard it from the personnel in qatar embassy here in the philippines when i inquire for procedure of visa stamping,,, im not sure if i heard and understood it correctly.
