The lawyer told our agency that our "pink slip" (which gives us permission to visit the Embassy to get Kevin's visa) will be requested Friday or Monday. This means that we will likely travel to Guatemala next Wednesday (if the slip is requested tomorrow) or Saturday (if the slip is requested on Monday.) Yeehaw!
P.S. We'll find out Friday evening whether the pink slip was requested or not so that's when we'll know what day to make our airline reservations for.
