Delgado (LIS) Portugal, Transit Visa Needed? A Lao PDR national and passport holder, current UK resident (have a BRP Card), leaving from Heathrow, transiting through Lisbon, and arriving in Chicago; I am in possession of a US visa. I don’t need a transit visa to go through Delgado in Lisbon from what research I’ve done. Can someone confirm? submitted by /u/orchand113
