Hi, thanks for doing this. Does having a special international tier status visa like a tier1 visa in the UK followed by a British Citizenship, help with getting an O1 visa in the US? Tier1 visa is pretty much the the UK equivalent of the O1 with a pretty comprehensive proof process.
There's no connection between the two - that is, no deference is given to those with a Tier 1 visa - but often those who qualify for a Tier 1 visa also qualify for an O-1 visa and - most importantly from my perspective - the Tier 1 paperwork can be reused to support an O-1 petition.
