The W2 says:If you have operational travel days outside the U.S., you may report on your Schedule SE a prorated portion of your wages based on this fraction: number of days of WBG work inside the U.S. during the calendar year / total number of WBG work days during the calendar year. Please note that you are responsible for tracking the number of your operational travel days outside the U.S., and you may wish to seek advice from a tax professional on the application of the operational travel reduction.
