Joe Bloggs or Terpe... need your help regarding dual Irish/British

[joebloggs]

You may only return to either (with non-EEA family member) if you have been in another EU state under treaty rights. Maybe that's why the Irish Embassy wanted evidence of previously exercising treaty rights within EU

Hope that makes sense and provide the answer you're looking for

Does that help you?

if you intend to come back to the uk with your wife from another EU country using the 'Surinder Singh route, you need to have been either self employed or have worked in the other EU country.
