So you don't think they can train in Europe for the US rules? They will have to clear multiple different rules depending on the country they are going to be going to. I guess you are not familiar with corporate training in one place to cover rules, regulations and procedures for many other. By your own statement the EU rules are more stringent so if they train for them then they most likely will be trained for other less stringent areas. Many companies and entities only train in one area. Saves massive amounts of money.
