The German Federal Ministry of Interior has decided to extend the border controls between itself and Austria for an additional six months.  As well as extending land borders, border control plan will be introduced for specific flights entering the country, namely flights from Greece. 

As a consequence, foreign nationals traveling in the Schengen area should carry their immigration documents with them (including passports).  Visitors should expect increased delays when attempting to enter Germany from German flights or when traveling through the Austrian border.
