Baby born outside UK to British Father and non British mother

[imme-123]

I am asking this on behalf of someone. The scenario is British male married to non British girl (Pakistani girl) in Pakistan. The male went to Pakistan and married there and lived there for few months after marriage. They had a baby (that was born in Pakistan). baby's mother never travelled to UK.

What is the immigration status of the baby born to British father.

If the father was a British citizen on the date of birth of the child, then the child is born a British citizen by descent and can apply directly for a British passport.

If the father became a British citizen after the date of birth of the child, the child has the same UK immigration status as that of the less-privileged parent (in this case, the mother).

I Will rephrase . If the father is British otherwise than by descent, then the child will be British, otherwise, the child is not.
