Naturalization is the acquisition of British citizenship by someone who held ,or continues to hold, foreign citizenship. There are several routes to naturalization. Adults may qualify for British citizenship through at least five years of residence in the UK, or through marriage to a British citizen (with three years’ residence in the UK as a spouse or civil partner).
In addition to residency requirements, naturalizing citizens must meet requirements of ‘good character’, ability to communicate in English , or Welsh or Scottish Gaelic, and ‘knowledge of life in the UK. Children may qualify for either automatic or discretionary “registration” as British citizens depending on the country of their birth and nationalities of their parents. Home Office administrative data counts citizenship grants of each of these types. Though registrations are not technically naturalization, at least in Home Office classifications, they are included with naturalization in this briefing.
In 2014, 125,800 foreign citizens naturalized as British citizens. This was a 40% decline from 2013, when citizenship grants reached almost 208,000, the largest annual number since records began in 1962. From 2009 to 2013, citizenship grants averaged 195,800 per year.
According to the Home Office (2014), the 2013 peak in citizenship grants followed an increase in applications in advance of changes to language requirements, while lower numbers of grants in 2014 were at least in part due to the shifting of resources from UK Visas and Immigration to HM Passport Office. Lower numbers of citizenship applications are also consistent with recent decreases in grants of settlement (from 241,200 in 2010 to 129,800 in 2012 and 154,700 in 2013), which will have reduced the pool of people newly eligible to apply for citizenship.
