I think the ramifications would be around the more general tenets of being a good employee which are "trustworthy" and "never making your boss look bad". For a hypothetical example, your boss and your company thinks you live in Vermont. One day, your boss' boss is impressed by your work (so efficient, so responsive during work hours) and asks her directly to bring you in for a look at another struggling project on the West Coast. He wants you to come in for an emergency triage/kickoff meeting tomorrow with herself, her boss, your boss, and the management of the current project. Problem is you live in Thailand... There is no good way out of the situation. You have been dishonest. Your make your boss look really bad by not being able to get you to communicate honestly (your location). You went to elaborate lengths to pretend to be in the US. In fact, to disguise your timezone difference, you were using photography lighting to make night look as day in your office in Thailand. You even scheduled your annual medical checkups to coincide with visits to the States. You will likely be fired or worse (sued) and blackballed in the whisper, word of mouth immediate network.
