(Was so hard to get over U.S. barriers in the form of h1b and later GC …)
Was so hard to overcome the English barrier … I struggled so very hard. Slowly I was able to express myself, with a big enough vocab…. Once the door crack opens, I got my first glimpse of a big, bright world behind the door. Immediately I could see myself thriving in that world.
With a safe retreat always available, there’s no real risk  to me so I boldly jumped in as soon as possible.
So which items in the 5advantages post? Job pool !
 Some people don’t need English and can do well using Chinese as primary language … I’m different.
 there’s indeed some risk to wife and to kids…
