The benefits administrator knows which countries are covered. Technologically, it is a trivial matter to update a web page (and note the date of the update) showing the current list of countries. For that matter, it would be a simple matter to show the history of the updates. And for another matter, it would be simple to show a list of all countries in the world where each country would be a link to that country's current status and history of changes. This type of information management is what computers do and this type of information dissemination is why the world wide web was developed.

That the benefits administrator chooses not to do this (and Chase chooses not to require the benefits administrator to do this) is a sad commentary on what passes for customer service.
