From the article...
“To keep H-1B workers in one place rather than see them scatter. To point them to a more-than-decent city and airport where they can move their work and live happily and access great public schools. We have this community here in Silicon Valley that we want to preserve and if you look at a map, there are few places other than Vancouver that qualify for this kind of move.”
We “aren’t saying to move on spec but to have a ripcord,” adds Rafer.
