Your friend should not waste her money. Her husband’s divorce lawyer will simply ask the Irish economist how many Irish illegals are there working in the US, and how many representations have been made by Irish politicians that they should be allowed to remain there. This could be interpreted as indicating a belief by certain Irish politicians that life in the US is better than life in Ireland. If it isn’t, why would they be making these representations? The divorce lawyer could also throw in a few questions on tribunals on corruption, tax scandals, etc. in Ireland. Your friends should face up to it that no rational U.S. judge would ever agree to American children being brought up in the land of paddywhackery and not in the home of the brave and the land of the free.
