Hi, yes, you can apply for an IVA whilst living abroad, but your main centre of interest, i.e. your main residency, has to have been been inside England, Wales or Northern Ireland within the previous 3 years of your application.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
