What European immigrants should know about the differences among Schengen countries, EU countries and the euro zone.

Schengen countries: If you have any one Schengen visa, you can avoid signing all other Schengen countries.

Euro zone: The euro zone means that the currencies of all countries in the euro zone are denominated in euros.

EU: Apart from their constitutions, these countries must abide by EU laws, including politics, economy, welfare and the treatment of citizens of EU member states.

Generally speaking, Euro countries, Schengen countries and EU countries cannot be equated.

For example:

Britain, which is an EU country, is not a Schengen country, not a euro zone.

So he spent pounds, he needs a British visa, and you are not allowed to enter the country with a visa from another country.

He is a member of the European Union. People from other EU countries go to Britain to cheat welfare in order to covet welfare. However, according to EU law, the British government had to let them cheat. Therefore, they can only be prevented from entering the country by various means.

Germany: All three.

So he uses euros, and his visa can go to other Schengen countries (there is no need to sign a Schengen country alone)

His welfare is not as good as that of Britain, so there are not so many cheating people.
