2004
Hungary is a member of the European Union.
Japan is not in the European Union.
On the 1st May 2004 Hungary joined the EU (European Union)
Romania, Slovakia, Austria and Slovenia are all members of the European Union and all border Hungary.
The European Union is an organisation for countries in Europe, so the US could not join. There are over 50 countries in Europe, 28 of which are members of the European Union. There is no reason why the US would even want to join the European Union. It would make no sense for them to do so.
No.

People do not join the European Union. Countries do. It is an organisation of countries, not of people. As a result of countries joining, people are living in countries that are in the European Union and can be called its citizens.
Desire to join the European Union. :)
