I think their intentions may be well meaning and some of their suggestions at first appear hilarious (for example, "open a window" I know some city dwellers never do because the outside air is so polluted where they came from). As a person who has travelled extensively and lived overseas in several cultures (including ones where as a white guy I was a spit upon visible minority), guides to how things may be different in the new culture / country are important and can be helpful. In Japan, they had to post "how to bathe" signs everywhere because of the number of idiot foreigners (Europeans, North Americans) climbing into the hot pools covered in soap. 

Instead of just giving to new immigrants, perhaps they should give the guides to everyone. I lost count of the number of times I encountered a foul mouthed B.O. smelling dirty haired "original" Quebecois. Or watched as some cringed when a person looking different than them sat beside them on the bus. Perhaps everyone would benefit.
