Form 80 is a 19-page biographical questionnaire. It is not always requested, but it is requested most often for partner visas, employer-sponsored visas and any case where the case officer has questions. Irish applicants tend to delay their own decisions on three fields.
§01Field 1: Addresses for the last ten years
Every address. Including the three months in 2017 living with a friend in Galway. Including the Erasmus exchange. Including the J1 summer in Boston. Use bank statements, Revenue records, P60s and college records to reconstruct. Gaps trigger character-check follow-ups.
§02Field 2: Employment for the last ten years
Every employer. Casual hospitality jobs, summer work in the UK, even unpaid internships. Match this against Revenue.ie My Account for tax records.
§03Field 3: Travel history
Every overseas trip, with dates and reason. Irish citizens' EU travel is usually unstamped, passport stamps alone are unreliable. Cross-check against bank statements (foreign transactions), Ryanair/Aer Lingus email archives, and Facebook check-ins if necessary.
