Hi,

Can someone knowledgeable please advise on whether it's possible to transit from one international flight to another at either Lahore or Karachi without passing through immigration/customs? I'm a US citizen thinking of flying from Colombo on a Sri Lankan non-stop to either Karachi or Lahore, arriving late in the evening (e.g., 2300), and then connecting on to an Etihad flight to AUH leaving around 0335 or so. Would I need a visa? Is that sort of transit possible if I'm on two separate tickets (setting aside the risks and consequences of a misconnect)?

Thanks!
