I am a US citizen who works in the United Kingdom. I have just submitted an application to extend my UK General Level 2 visa and have gone to the appointment to take my fingerprints / photo and scan my passport and the current BRP.
My current visa does not expire until the end of January. However, I will be in the USA UU For holidays, I will return to the United Kingdom while my current visa is still valid. But there is a possibility that my extension will not be approved before I go to the United States.
My question is: what will happen if my extension is approved while I am abroad? When I return to the United Kingdom, will my passport be automatically marked as a problem? What would I have to do at the airport to be able to re-enter with my current (or new) visa?
Any info is greatly appreciated.
