Although the original plan was for the Schengen Area to open its air and sea borders with Bulgaria and Romania by March 2012, and its land borders by July 2012, continued opposition from Germany, Finland and the Netherlands has delayed the two countries' entry to the Schengen Area.
Meskipun rencana awalnya merupakan upaya Kawasan Schengen dalam membuka perbatasan udara dan laut dengan Bulgaria dan Rumania di bulan Maret 2012, serta perbatasan darat di bulan Juli 2012; pertentangan terus menerus terjadi di Jerman, di mana Finlandia dan Belanda menunda masuknya kedua negara tersebut dalam Kawasan Schengen.
