How to Apply for British Citizenship by Double Descent

When applying for British citizenship individuals may find themselves with a difficult choice to make between which route applies to their unique case, as each British citizenship route has its unique requirements and legal criteria. British citizenship is usually obtained via one of two routes: by descent or naturalisation. British Citizenship by decent means that individuals born outside the UK to British parents, may be eligible to claim citizenship, as their lineage offers a direct route to satisfying the requirements needed. British Citizenship by naturalisation includes a wider variety of individuals aiming to apply for citizenship, visa routes such as a spouse or skilled workers, or the likes of long residency in the UK.

What is British Citizenship by Descent?

British citizenship by descent allows individuals born outside the UK to inherit citizenship through their British parent. This pathway is eligible to those who meet the given requirements, even when born abroad, meaning they can claim British citizenship. It generally applies to the first generation born outside Britain, governed by straightforward rules on parental citizenship.

When Does Double Descent Apply?

British citizenship via Double descent is a much complex and niche route designed for those aiming to claim British citizenship through a grandparent. This approach looks deeper into family lineage, extending beyond immediate parents to British grandparents. According to the British Nationality Act of 1981, the usual basis for obtaining citizenship from birth outside the UK is having a parent who is a British citizen “otherwise than by descent”. However, certain exceptions can facilitate claims of double descent, incorporating historical and personal circumstances that might allow second-generation descendants born abroad to qualify for British citizenship.

Key Document Requirements

The process of claiming British citizenship by descent necessitates the applicant to gather a variety of key documents for the application, which are crucial for establishing the required familial connection. These documents typically include but are nor limited to:

  • Birth Certificates: To prove the applicant’s birth and lineage.
  • Marriage Certificates (if applicable): To document the marital status of parents or grandparents, relevant in some cases of citizenship claims.
  • Evidence of British Parent or Grandparent’s Citizenship: Such as their birth certificate, citizenship certificate, or passport details, providing proof of their British nationality.

These documents form the foundation of an application for British citizenship by descent. The eligibility for claiming citizenship by descent is largely dependant on presenting clear, unambiguous evidence of the applicants British heritage through parental or grandparental lineage.


Eligibility Criteria for British Citizenship by Double Descent

The eligibility for British citizenship by double descent requires the applicant having an understanding of the distinct criteria based on the applicant’s date of birth. The British Nationality Act of 1981 lays out these requirements, which vary significantly for those born before and after 1st January 1983

A. Requirements For Applicants Born After 1st January 1983

For individuals born after this date, their eligibility is based on specific circumstances related to their grandparents and the nature of their parents’ citizenship. The conditions include:

  • Grandparent in Crown Service: Eligibility if the applicant’s UK-born grandfather was serving in the Crown Service at the time of their parent’s birth.
  • Birth in a Former British Colony: If the applicant or their parent was born in a former British colony, this may qualify them for citizenship by double descent.
  • British-born Mother: If the applicant’s British-born mother was registered as a British citizen between 2nd February and 31st December 1982, this offers a route to citizenship.

B. Requirements For Applicants Born Before 1st January 1983

Individuals born before 1983 may also have potential routes to British citizenship by double descent in which they can apply for under conditions that reflect historical links to Britain and its former territories. These include:

  • Former British Territories: Eligibility if the applicant or their parent was born in a former British territory, excluding main Commonwealth countries of 1949.
  • Parent in Crown Service: Similar to those born after 1983, if the applicant’s parent was in the Crown Service at the time of their birth, this may qualify them.
  • Marriage Before 1949: If the applicant’s parents were married before 1949 and their father was born in the UK, this is another potential route.
  • Non-EEA Birth with British Maternal Grandfather: Eligibility for individuals born outside the European Economic Area (EEA) if their mother’s father was born in the UK.

These mores strict and specific criteria demonstrate the complexity of applying for British citizenship by double descent. Each case requires careful consideration of historical and legal nuances.

While pursuing British citizenship by double descent is a viable pathway for many, it’s important to recognise alternatives that may suit different circumstances or eligibility criteria. One possible option is the UK Ancestry Visa, which provides a route for individuals with British ancestry to live and work in the UK, potentially leading to citizenship.

This visa is designed for Commonwealth citizens with a grandparent born in the UK, the Channel Islands, the Isle of Man, or in what was then a British territory.

  • Age Requirement: Applicants must be 17 years or older.
  • Commonwealth Citizenship: You must be a Commonwealth citizen to apply.

Benefits and Pathways

  • Duration and Renewal: The Ancestry Visa is initially granted for 5 years, after which applicants can apply to extend or seek permanent residency, eventually leading to citizenship.
  • Family Inclusion: Dependents can accompany or join the visa holder in the UK, provided financial support is demonstrated.
  • Work and Study: Visa holders have the right to work, study, and even start a business in the UK.

Application Process

Applying for the UK Ancestry Visa involves:
  1. Documentation: Gathering evidence of your ancestry, financial means, and intention to work.
  2. Application: Completing the application online, followed by submitting biometric information.
  3. Fees: Payment of the ancestry visa application fee is £637 (as of the last update) plus the immigration healthcare surcharge.
