Question: is indefinite leave to remain the same as right of abode

Answer: No, Indefinite leave to remain (ILR) or permanent residency (PR) is an immigration status granted to a person who does not hold the right of abode in the United Kingdom (UK), but who has been admitted to the UK without any time limit on his or her stay and who is free to take up employment or study. When indefinite leave is granted to persons outside the United Kingdom it is known as indefinite leave to enter (ILE).
