A Pakistani friend who needs to go to India was informed (very late, near visa approval) by an Indian embassy official (in Singapore) that he can only enter* India through one of the four major airports: Delhi, Mumbai, Kolkata and Chennai.
* By "enter" I mean that the immigration officers (perhaps the equivalent of "customs agents" in the US) will allow the person to enter the country through the immigration checkpoint of an airport, or be detained at the checkpoint and barred from entering the country. This is not related to "customs" which deals with importing goods, or to being inside a flight that lands at the airport.
Direct flights to and from a smaller airport were already booked, which are now being changed to two-stop flight plan landing at one of the four ports internationally then transiting to a domestic flight to the original destination.
We searched online for any information about such restriction but could not find any. Is this restriction as per Indian law? Where can a reference to this restriction be found?
customs-and-immigration
(border control procedures; referred to as 'immigration' in most countries other than US) appears to be a better tag thanregulations
(Rules, regulations, and policies of organizations as opposed to laws of nations or governments.).migration
tag could be synonymous with immigration (with a note that it means the act of moving permanently, and one must not use it for checkpoint issues). And there could be animmigration-checkpoint
orimmigration-entry
tag specifically for the act of getting approved at a port's checkpoint to enter a country through the port (air/land/sea). And then acustoms
tag for issues about customs (importing goods) and dutiable goods. It could be a good meta discussion.
