An accompanying relative is a family member who is permitted to travel to, enter or remain in a jurisdiction alongside a primary migrant or applicant, such as a worker, student, refugee or patient. In UK and Irish immigration law, the concept appears mainly in rules and policies on “dependants” or “family members”, rather than as a stand‑alone defined term, and may include a spouse, civil partner, unmarried partner, child or, in limited schemes, other close relatives.The status and rights of an accompanying relative depend on the underlying route (for example, Skilled Worker, International Protection, EU Settlement Scheme, or Irish employment permits) and the specific statutory instruments, Immigration Rules, Home Office/UKVI guidance, or Irish immigration policy governing that route. Typical issues include eligibility criteria, evidence of relationship, financial requirements, rights to work or study, and consequences if the primary migrant’s status ends.Usage is broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, though the detailed categories and conditions are jurisdiction‑specific. Practitioners should check the applicable legislation, rules and guidance for the particular visa, protection claim or cross‑border movement being advised on.
