Residence Cards and Permanent Residence
Although most EEA nationals are not formally obliged to apply for a residence card to live and work in Scotland / the UK, it might help you re-enter the country more quickly and easily if you travel abroad, as well as show employers you are allowed to work in the UK.
Some EEA nationals will also be eligible to apply for a Permanent Residence card. This will certify an individual's right to live in Scotland / the UK on a permanent basis and any EEA national seeking to apply for British nationality will usually be required to provide a Permanent Residence card.
In various circumstances, it is possible for EEA nationals to acquire British nationality in addition to their own nationality. There are various criteria to be met and it usually requires the applicant to have been resident in the UK for at least 6 years prior to applying.
