European Economic Area citizens who wish to submit applications for British Naturalization can do so but first, they need to apply for a document which will confirm that they are completely free from any kind of Immigration restrictions, and when they are ready to submit applications for the British Naturalization proper, the document must be presented to the authorities as part of their application package.
When submitting applications for British Naturalization, citizens of the European Economic Area who have already been granted their Permanent Residence status under the 2006 EEA regulations with the conditions of having resided in the United Kingdom continuously for a period of five years, will in addition have the need to prove that they have also completed another 12-month period of residence in the United Kingdom. Important to note that this period can only be considered if it is completely free from immigration time restrictions of any kind.
