I have been unable to find an answer to my question on the UK immigration web pages, nor on other travel stack exchange questions/answers, so any help would be much appreciated.
I have entered the UK on my Australian passport. However, since entering I have been granted EU (Czech) citizenship. Do I now have the rights of an EU citizen in the UK?
Basically, does EU immigration law mean that am I strictly bound by the rights/restrictions of the passport I enter the UK on, or do you automatically possess EU rights if you are/become an EU citizen while in the UK, irrespective of what passport you entered on?
Note: I do not have a Czech passport (yet), so I cannot exit the UK and re-enter on that passport. Note: I'm not trying to find out information about the future impact of Brexit, just trying to find out information for the current situation while the UK is still part of the EU.
