Applying to Naturalise in the UK – One of the processes of obtaining British citizenship is via naturalisation. This is when a non-citizen of the UK has permission to acquire citizenship. The most common ways of naturalisation are under the 3 year rule or the 5 year rule. The 3 year rule is on the basis of being married to a British Citizen and holding Indefinite Leave to Remain (ILR) before the July 2012 rule change.

Routes to Naturalising as a British Citizen

3 Year Rule

The applicant must be married to a British citizen, hold ILR and have resided in the UK for a full 3 years.  The three year rule is only applicable for those who came on a settlement visa prior to the rule change in July 2012.

Is on the basis of having held Indefinite Leave to Remain (ILR) or Permanent Residency (for EEA Members and their family members) for at least 1 year after previously spending a continuous period of 5 years on a visa that leads to permanent settlement, such as those on work related visas or those who have applied for a probationary settlement visa after the July 2012 rule change.
