Understanding the Schengen Area and Spain's potential suspension
The Schengen Area functions as a travel zone across Europe where passports are not required, enabling more than 450 million individuals to travel between 29 different countries without undergoing standard border inspections. This group includes 25 members of the European Union along with four countries outside the EU. Although routine checks at internal borders have been removed, all participating nations adhere to shared regulations regarding external border protection and visa policies. Currently, Spain faces the possibility of being suspended from this agreement due to the ongoing surge in migration.
