Settled statue

Hi,

I wanted to ask about my mother who is 83 years of age and has a settled statues for the past 1 year . She came to U.K. in 2015 and then I wanted her to stay with me as she had no blood relative in Pakistan . My sister lives in Denmark and we apples with the eu rules . I wanted to apply for my mothers naturalisation now . How can I ?

First review the official guidance for naturalisation applications - Form AN:

Note that your mother won't have to take the English and Life in the UK tests!
Note also your or your sister's status are not relevant to your mother's application - she applies in her own right.
