It's been consistently shown that refugees are a net economic benefit.
Here's a recent brief which describes the economic impact in Lebanon, which has taken in the equivalent of a quarter of its population.

The Vietnamese refugees of the late 1970s early 1980s had the same language and cultural issues. Many could speak French, but language skill varied. It did not take them that long to adapt.
My parents, who were in their early 20's, were Vietnamese refugees in the early 80's. They were sponsored by a Mennonite church community in rural Saskatchewan. The group helped them out with accommodations, English classes, and gave them their first jobs around the farms.
A few months (years?) later, they moved to Saskatoon. My dad attended college, and eventually got a job at the University of Saskatchewan. My mom worked odd jobs then eventually got a job at the University as well.
They are very thankful of the help that they received from their sponsors and the Government, and could not be where they are now with the initial help they received.
We call ourselves Canadian, and my family is proud of it.
