A residence card confirms the right of an EU citizen's family member to live and work in the UK for 5 years, making it easier to prove this right to employers and officials. To qualify for permanent residence, an applicant must continuously reside in the UK for 5 years with limitations on absences, though employment alone may not be sufficient if migrant worker registration is required. When dependent on an EEA partner or spouse, their residency and employment must meet the criteria. It is advisable for those eligible to apply for certification of permanent residency from The Abbey Law Firm.
