I am coming to Pakistan from the US this August. I have two laptops, on DSLR and three tablets with me that I plan to take in my back pack (I have already rehearsed that so don't worry about how would I manage it). Can anyone please tell me how many tablets and laptops are allowed custom-free these days? What kind of problems I may face on Karachi airport. In case your answer is that this quantity is not allowed, is there any way I can bring all this stuff to Pakistan ?
