The european union wants trump to visit them immediately

I think there may be some confusion here.

To clarify, there is no evidence to suggest that the European Union (EU) has made a formal request for President Trump to visit them "immediately". While the EU and the United States have a long-standing relationship and cooperate on many issues, there is no indication that the EU has made a specific request for a visit from President Trump.

It's possible that you may be thinking of a different event or development. Could you provide more context or clarify what you're referring to?
