Get your facts right please. Most Syrians are, as of March 2023, in İstanbul, Gaziantep, and Urfa. Then Hatay. Majority of the Syrian refugees that are housed in Hatay are the relatives of the Shia community of Hatay.
Turkey hosts more than three million Syrian refugees. For a long time, the official political discourse was rather welcoming. However, this has changed in recent years.

Hatay has a big population of Syrians living in camps. Hatay’s own Arabic origin population are loyal TR subjects and having seen the mess in Syria, they are even more dedicated to Turkiye. Apart from that, they are Shia Muslims and do not like the predominantly Sunni Syrians that have sought refuge in Hatay. They see themselves as devout followers of Atatürk‘s principles. There aren’t many stray Syrians like in İstanbul or Antalya, in Hatay; apart from the rich ones that have rented villas etc. I have seen the use of daily arabic language less and less by the locals in Iskenderun after the influx of Syrians. Where as you would have heard more Arabic spoken amongst locals in and around the city, say 15 years ago, now there is more tendency to speaking Turkish even amongst each other, to isolate themselves from the Syrians.
