1) Poor internet connection 2) Client timezone shift 3) Work vs. vacation visa challenges. Issue 1 is fairly fluid. Telecommunications infrastructure is constantly being upgraded, so internet connections tend to improve over time. Timezone shift is a challenge. Expect to take some late night calls with clients (or early morning). I never overstayed a vacation visa, but the horror stories from digital nomads most often are related to securing and renewing a work visa. This is easily avoided by never taking income from the local economy, where taxes may be required.
