I am traveling to Cork, Ireland on a short stay (C) visa. It is not a biometric visa. I hold an Indian passport and am traveling from USA where I am a permanent resident (green card) holder. I am transiting through London Heathrow. Do I need a UK transit or short stay visa? The information on the gov.uk website is quite confusing when it comes to transiting to Ireland due to common travel area reasons.
But, most documents/websites I have seen indicate that anyone with a valid US green card issued after 1998 are exempt from needing a visa (https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/648410/UK_Visa_requirements_Oct_2017.pdf) and can transit without visa (TWOV).
Can someone on this forum please confirm this?
