Yes, there were a lot of language barriers, but after I had found a foreman who speaks English and connected them with him, they performed perfectly. The people who worked with the Arabic employers performed even better. Because the training comes from the Arabic employer himself, it requires less investment to train them. In that sense it was an extreme success.
One of the older Syrian refugees, who I tried this pilot program on, is now working with a non-Arabic-speaking company. He's a professional painter. He knew nothing about painting and is getting paid $20 and something an hour. There is success, if we actually focus on the employment sector.
