If travelers wish to visit the European Union and have a non-EU passport, there can be some obstacles. Getting the Schengen Visa—depending on where you come from—can be a challenging process, but there are additional steps any foreigner may need to take before traveling.
Unknown to many, travelers visiting from third countries (countries outside the EU) may have to prove they have 100 Euros per day of spending money to enter EU nations like Spain and France.
For many travelers, this isn’t an issue; for budget travelers, this could cause some problems.
According to EU law on entry from third countries, travelers from non-Schengen and non-EU nations technically need to show proof of financial support for their entire stay in the Schengen Zone.
They will be doing random checks apparently.
This is similar to Uk for certain countries, my nephew’s friend always has to prove this when travelling on his Australian passport
