In my experience, trying to speak in a language I am not as comfortable in makes my stutter even worse. What about you? Is this a foreign language situation? Have you discussed your stutter with your potential employer? Do they know how severe it is? They really need to know, or your job would probably be in jeopardy once you get there and they realize the scope of your abilities. If the job pays well, keep in mind you can hire someone to help you manage your personal affairs, if you are truly not capable of doing certain things. From a psychological perspective, I can only imagine how tough this is. My stutter is not as severe as yours, I suspect. But look at it this way - you are still way more capable than a deaf person. And deaf people often do fine.
