If kids are born in UK from non British parents, how do they get citizenship?
Just stay in the UK. If such a person remains in the UK for the first ten years of his or her life, and is not absent from the UK for more than 90 days during any of those years, then he or she is entitled to apply for registration as a British citizen.I see this answer has been collapsed by down votes. The answer is true, accurate, and is, without doubt, the easiest way for kids born in the UK from non-British parents to get UK citizenship. Before downvoting, read the reference, which is from the government of the UK. From that reference:“You lived in the UK until you were 10You can register to become a British citizen if you were born in the UK on or after 1 January 1983 and neither of your parents was a British citizen or settled at that time.You must:be 10 or olderand have lived in the UK until you were 10 or olderYou must also normally have spent no more than 90 days outside the UK in each of the first 10 years of your life.If you spent more time than this outside the UK but there are special reasons for this, you’ll need to explain them on the form.Apply using form T. Read the guidance before you apply.”Register as a British citizenYou can find the form and guide here:Application to register as British citizen: form TI will, however, add Sue Ambrose’s caveat that “it is best to take advice from an immigration lawyer based on your own and the child’s/children’s circumstances.”
