So much this. It's not just important to be okay at communication. I've had coworkers in the U.S. that were immigrants and it was absolutely painful to work with them to the point, where we actively just excluded them. We just found human cron-job tasks and relegated them to those tasks (unfairly, but better than laying them off). In things like software, where there are many many abstract concepts being thrown around, not being able to communicate will get one quickly out the door.
