Hi,

My parents from India would be visiting me shortly in US. On their way back to India, they want to stop over in UK for few days. What visas would be required for them? To visit UK do they have to get any visa from India, or do they have to get the Visa from US?

Please reply

Yes, they will need a UK Visa if they hold Indian Passports.
Best Bet contact the UK Consul General to see if they will issue a tourist visa
