When we travel abroad, we always register our stays/travels with the US Department of State. So, just in case something happens while you’re in-country (conflict, weather disaster, etc.), the DOS knows where you might be and can get to you. It’s also a great way to get country information straight from the embassy, which would include any disaster/security alerts you’d want to know about. Both of us had to register separately, inputting 28 different places. Which triggered a lot of emails! 📧
