Is it feasible to go to Guam from Korea?

No, you must apply for an American visa.

Korea doesn't need a visa to go to Japan, yes, but it must have a Korean passport. Or, if the company gives you a Korean immigrant visa, that's fine. Otherwise, you definitely need a visa.

If you are not a Korean passport or a Korean immigrant visa, you must apply for a visa in China. Of course, having a Korean visa helps to get a US visa.
