I have a flight which originates from Dallas, goes to Paris, and from Paris gets to Bangalore via London. The transit time is less than 3 hours and I will not have any check-in luggage (so no border control?). As per my understanding I should be exempt since I have a valid US visa. https://www.gov.uk/check-uk-visa/y/india/transit/no
But my travel agent says I need a transit visa for London. Does anybody know the updated rules for transit?
