The other posters' changed examples are just fine but if you wish to use "will" or "would", you might change it to read:
I might be willing to go to America next year if it
would further my professional life/career.
Note that I've used "would". I'm always confused when this question is raised (and it comes up all of the time, Hierophant, so you're not alone

) if only because of the introvertible meaning of "will" in this context. "Will" means that you have
agreed to do something. That you are
going to do something. That you have
made the decision to do something.
"Would" is not so final in this context (you will notice that it's used with "if). There is possibility with "would" and no flexibility in the word "will" ie:
Wife to Husband: "
Would you please go to the store and buy a carton of milk?" (she is asking if there is the possibility that her husband will do this for her).
Husband: "I
would but I'm watching the football game right now" (he is saying that it's a possibility that he might do it if the game weren't on)
Wife: "You
will go the store or else...!" (she is saying that it's no longer a mere possibility - that he
will go if he knows what's good for him)
Husband: "You're right, dear. It's almost half-time and I
will go then" (he's saying that he
will do it)
