If he’s Syrian in Kuwait then he most likely doesn’t have any legal standing to live there. You can google info about the situation. Before the war in Syria there were Syrians living legally with work permits in Kuwait. After the war, about 2015 or so, there was a huge influx of Syrian refugees and Kuwait was kind enough to cancel all the work permits of the other Syrians already there.
Kuwait, and other ME countries, caught a lot of shit for refusing to take Syrian refugees. Europe took far more. Kuwait even started shipping then back to Syria which resulted in some major flack. As a result they stopped deporting so many, but they also refused to accept them as refugees and give them any legal standing. It’s estimated there are “about 160,000 Syrians expatriates who have overstayed in Kuwait.”
Salad would a very, very rare bird if he was there legally. However, the fact he’s a man of conscription age that has not served in the Syrian army means he’s illegal. Syria would not renew his passport to allow him legal residency in Kuwait. He’s required to return to Syria to do his required stint in the army and that, among many other reasons, is why he remains in Kuwait and wouldn’t have a valid passport.
Someone did mention that Canada did rant refugee approval to many Syrians IF they can find a sponsor. So Salad might be able to travel to Canada if that is the case and Chantal has all but admitted they have been figuring out how she can be his sponsor.
