What are the differences between the following sentences according to their meaning?
1- I have been in UK.
2- I have been to UK.
I am not a teacher.
Firstly, the definite article is required in both of your sentences. It's the UK.
1- means you have spent time in the UK and 2- means that you have travelled there.
2- is natural as a stand-alone sentence whereas 1- isn't, although it would be grammatical with the 'the'.
It would be more natural in a full sentence such as, 'I have been in the UK since last Thursday' or, 'I have been in the UK for a couple of weeks'.
