Close. You can take the second year pay, and incur an 18 month commitment. You can also forego second year pay, and bid back at any time. OR You can take the one-way move and also incur an 18 month freeze. The freezes will run concurrently, not consecutively.

That said, a one-way move for a full home will run almost $100,000, and if you leave early, you have repay all of it. It is NOT prorated.

As far as health care goes, Guam definitely lacks in some of what the States have. The company clinic here is quite good, but it's not a full-blown ER ward. If you have a serious problem, you are either going to Manila (there's a first class hospital there) or HNL. There are provisions for emergency transport out, but the reality is that some of the health care leaves a lot to be desired, and there are some specialists that the island does not have, such as a pulmonologist, and there is only one anesthesiologist.
