It's very typical for a candidate to learn his status once in a while. I'll call HR first, and if they don't know, I'll talk to the hiring manager. I won't raise English as an issue. Once you raise it as an issue, it becomes an issue. Instead, just tell them you are really interested in the opportunity. Show enthusiasm. If you suspect that they worry about your English ability, just talk fluently.
Things may be brghter than you think.
