Deportation Action Plans

I recently heard a story on NPR concerning "deportation wills." When someone is deported, he may have substantial assets that need to be disposed of appropriately. For example, someone may own a house, a car, a business, some real estate. He may have children. A deportation action plan is a combination of legal instruments designed to protect a deported person's assets and children. It could involve setting up trusts for property, guardianships for children, powers of attorney, contracts to protect business interests, and probably much more. This seems to be a very new area and there is not much information on it. If anyone has any thoughts about this topic, they would be very much appreciated.
