An interesting offer, I need some advice.

From the prospective of a 67 year old retired aerospace engineer, project manager, and manufacturing VP, it would seem to be a very valuable investment of 3 years delay to become an accomplished Chinese speaker in today's world. Your cross cultural knowledge and language skills will put you way ahead of your competition in many, many areas of U.S. business you may pursue. Due to military service, I did not start my career until 28. The early years of experience are usually totally discounted by any hiring manager and only used to gauge whether you were mature and responsible to use them wisely. This opportunity sure sounds mature and responsible to me if you don't have to separate from your spouse to pursue it.
