Hi, I bought a travel itinerary online. The itinerary had a PNR which was verifiable for 2 weeks. I got the verifiable itinerary pdf from Qatar Airways website and attached it to a document that I wrote to explain my purpose of travel. Now my question is will the travel itinerary be an issue since after 2 weeks it is not verifiable? Do the visa officers verify the PNRs? or do they verify E-tickets?
