It's very difficult to tell who is entitled to what tbh, as the whole system is such a mess. For example, statistically, Costa Ricans were more successful at claiming asylum than Iraqis for about three months last year.
It's also difficult to tell what nationality the Kurds in Calais are, often; many go from Turkey to Iraqi Kurdistan and then on to Europe; many Syrian Kurds spend some time in Turkey trying to make life work before moving on- in the camp the Kurds tend to stick together and describe themselves as Kurds. There are a few exceptions- Syrian Kurds who stick with the Syrians, mostly. But on the whole if you're describing the camp you say Syrians, Iraqis, Sudanese, Eritreans, Kurds... And there are two Kurds I know are Turkish who say they are Iraqi- they lived there a long time so I imagine no one will catch them out this side; but a Syrian Kurd is certain they are Turks. It's a murky old place over there.
