ISTANBUL, TURKEY - MAY 04:  A man holds a Visa application form as he waits in line outside a Joint Visa Application center to apply for a Schengen visa on May 4, 2016 in Istanbul, Turkey. The European Commission today recommended Turkish citizens be granted visa free travel for short stay, business and tourist trips to Europe's Schengen area, as part of the EU-Turkey migrant deal. EU member states and the European Parliament are set to vote on the visa deal in June. (Photo by Chris McGrath/Getty Images)
