I want to travel to India from Switzerland via London, so do I need a transit visa for UK ? My onward flight from London is from same terminal within 3 hours. I am an Indian National having a residence permit B issued by Switzerland. I read that having "a common format residence permit issued by an European Economic Area (EEA) country or Switzerland" are exempted from transit visa.
But I am not sure if my residence permit is a common format resident permit and falls in this category. Kindly advise if someone know about this. Thanks.
