Will my life insurance be void if I move or change jobs?

I work in Asia. When I applied for life insurance in the U.S. right before leaving my premium skyrocketed when they heard I'd be working in Asia as a teacher. I'm a U.S. citizen. I'll be going back to the U.S. for a few months to work a different job. While back, could I apply for a new policy somewhere else and get a "normal" premium? I'm young and healthy and feel like I'm getting ripped off big time even though I shopped around for the best deal. I intend to go back to Asia several months later to continue teaching. When I do so, could that nullify the new policy? That is what I'm afraid of.
