This ... and I don't think it's unfair to expect such.
I've just finished a year's contract in Iraq for a major Oil Co. We employed several Syrian lads, generally as engineers .. good lads. They were well mannered, hard working, basically very employable. Their families bailed out of Syria many years ago so they had spent their formative lives in neighbouring countries (Lebanon, Turkey, Jordan etc) where they'd been educated and acquired their skill.
There was a time when we considered employing lots of young engineers and went through due process and asked for their input. They were highly resistant to employing fellow Syrians under the age of 30 who had not grown up outside of Syria as they had probably little or no acceptable education, knew only conflict as that's what they had grown-up with and had 'that' mindset. Also they were typically 'work shy'. The same could be said of Iraqi men (the majority of whom are less than 30 y/o anyway). We didn't hire any.
Why would we welcome anyone to the UK who offers nothing but 'risk' and liability ? Don't we have enough already ?
