These three countries have significantly contributed to the well-functioning of the Schengen area for years. They've performed well during the pandemic and when faced with the unprecedented consequences of the war in Ukraine. Through reinforced protection of the common external frontier, an enlarged Schengen area without internal borders will make Europe safer and more attractive to businesses. It's time to also welcome Romania and Bulgaria into the passport-free Schengen Area.
At this point, it doesn't make sense to enlarge the EU's free-travel zone when it's clearly not working. Europe hasn't yet recovered from the 2015 influx of hundreds of thousands of people fleeing war and poverty in Syria, Afghanistan, and the African continent. Austria is still struggling to accommodate asylum requests, having more than 100K illegal border crossings this year alone. Admitting Bulgaria and Romania would only increase this irregular immigration.
