My wife will be applying for a UK residence card soon. She is Argentinian. I understand that the HO will keep both of our passports (I am the British citizen) until the decision is made.
Is there any possibility of her getting her passport back so that she can go to Argentina for a family event? Alternatively, would a copy of her passport satisfy airlines/border agency etc? She has an Argentine ID card, which will suffice for getting in and out of Argentina with the passport copy, but I doubt that would be acceptable here.
