Backstory
US Citizen (and passport holder) applies for an academic (business) visa and is declined on the grounds that they are not on sabbatical leave. However, they are a professor teaching online in the USA so are able to be abroad and do research. So the visa was declined, and as there is no right to appeal the US Citizen just leaves it. Academic visas don't have a right to appeal.
They applied for the visa so they could be in the USA from January to August in the same year, so needed it since they can only travel to the UK without a visa for a maximum of 6 months.
Question
They plan to visit the UK to see friends.
- Can they enter the UK without a visa?
On the gov.uk visa check it says:
You may want to apply for a visa if you have a criminal record or you’ve previously been refused entry into the UK.
However being declined a visa is not the same as refusing entry right?
If not, what visa would they have to apply for? And will the below effect which visa it would be?
They have now married a UK citizen who has since moved to the USA, and holds a US green card (through marriage). The UK citizen is permanently residing in the USA, but receives income from the UK.
