I am an Indian citizen. I am going to India on a vacation. I am planning to have my flight via London. I've a layover there at London for almost 5-6 hours. I have a visitor's visa for UK but not planning to visit the city this time, my concern is that my H1 stamp on my passport has expired.
Can I pass through London with expired US visa stamp on my passport as I have UK visitor's visa on my passport?
