Europe’s migration debate is increasingly affecting one of the European Union’s most visible achievements: the Schengen system of passport-free travel.
Following a major increase in irregular arrivals, several countries have introduced or extended temporary controls at their national borders. Governments say the measures are necessary to address irregular migration, security concerns and the movement of migrants between EU countries.
The renewed border controls have raised concerns about the future of free movement inside Europe. Supporters say temporary checks can help governments manage security and migration pressures, while critics warn that repeated restrictions could weaken the principles behind Schengen.
At the same time, EU governments are working on a broader system for sharing responsibility for asylum seekers, including relocation, financial contributions and other forms of assistance.
The coming months are likely to be important for determining whether Europe moves toward greater cooperation or increasingly relies on national border measures.
