The process of naturalisation in the UK usually follows specific eligibility criteria. However, in certain cases, the Home Secretary has the authority to exercise discretion in granting British citizenship. This section outlines the scope of this discretion, the factors influencing such decisions, and examples of scenarios where discretion may be applied.

Factors Considered in Discretionary Cases

Examples of British Citizenship by Discretion

  • Exceeding Allowable Absences:
    • Applicants who have lived in the UK for many years but slightly exceeded the allowed absence limit due to extenuating reasons.
  • Significant Contributors with Limited Residency:
    • Highly skilled individuals with substantial contributions to the UK but lacking in meeting the residency requirement due to international work.
  • Lack of Documentation Due to External Factors:
    • Applicants with a strong claim to citizenship but unable to provide necessary documentation because of factors like political unrest or natural disasters in their country of origin.


Each case is evaluated on its individual merits, and there’s no assurance of success even if it seems to align with discretionary criteria. Understanding these nuances is essential for applicants considering this route for British citizenship.
