If you were born in the UK before January 1, 1983, you are normally considered a British citizen and do not need to submit an application to register your citizenship. As identification, you can apply for a British passport.

If one of your parents was a British citizen or had already established residency in the UK when you were born in the country on January 1 1983 or later, you should automatically be granted citizenship and be eligible to apply for a passport.

However, if you were born on or after January 1, 1983, and you are under 18 and one of your parents has since become a British citizen, obtained a visa to permanently reside in the UK, or you resided in the UK until you were at least 10 years old, you may need to register as British.

Registration as a British citizen under the age of 18 years

You must be under 18 years old when you submit your application.

Once you turn 18 years old, you must submit an application for British citizenship as an adult, either by registration if you qualify or through naturalisation.

If one of your parents believed the UK to be their home, and you were born on or after January 1, 1983, you might be able to register your citizenship if any of the following happened to one of your parents after your birth:

• They acquired British citizenship
• They received permission to stay in the UK indefinitely (Indefinite Leave to Remain)
• Under the EU Settlement Scheme, they received settled status, known as Indefinite Leave to Remain (ILR)

Registration as a British citizen if you lived in the UK up until the age of 10.

If you met the following requirements and were born on or after January 1, 1983, and resided in the UK until you were at least 10 years old, you may reapply to become a British citizen:

• Your birth date in the UK falls on or after January 1, 1983
• You are 10 years old or older
• You have a good character
• The Home Secretary may make an exemption to this rule in exceptional circumstances if you haven’t spent more than 90 days outside the UK in each of the first 10 years of your life

If you were born in the UK on or after January 1, 1983, and one of your parents was a British citizen or had already made their home there, you might automatically be considered a British citizen and won’t need to submit an application to register for British citizenship.

To be settled in the UK implies having no temporal constraints. This includes those who hold a right of abode, permanent resident status, indefinite leave to remain, or established status under the EU Settlement Scheme.

In some situations, you can apply for a UK passport or even a letter confirming your status rather than registering for British citizenship.

You must fill out Form MN1 and provide proof that your kid meets the necessary eligibility conditions, either by birth or adoption, in order to register them for British citizenship.

When filing Form MN1 for their child, a parent may also seek for British citizenship using Form AN (British citizenship by naturalisation).

Parents need to be informed that while their child might be accepted for registration, their personal application might be rejected. In this situation, the parent is asked to confirm in Section 7 of Form MN1 that the child should still be registered as a British citizen.

When the parent’s application is rejected, the child’s application will be viewed as having been withdrawn if the appropriate option is not checked. And there will be no refund of the child’s application fee.

When a person becomes 18 years old, they can apply for British citizenship as an adult. If they are eligible, they can register, or if not, they can naturalise. They must use Form AN rather than Form MN1.

• It costs £1,206 to register a British citizen as an adult, and
• £1,012 for a child under 18 years applying to register as a British citizen
