The U.S. Department of State encourages all U.S. citizens living abroad to register with their nearest Embassy or Consulate.
From their website:
https://travelregistration.state.gov/ibrs/home.asp"When an emergency happens, or if natural disaster, terrorism, or civil unrest strikes during your foreign travel, the nearest U.S. embassy or consulate can be your source of assistance and information. By registering your trip, you help the embassy or consulate locate you when you might need them the most. Registration is voluntary and costs nothing, but it should be a big part of your travel planning and security.
U.S. consular officers assist Americans who encounter serious legal, medical, or financial difficulties. Although consular officers cannot act as your legal counsel or representative, they can provide the names of local attorneys and doctors, provide loans to destitute Americans, and provide information about dangerous conditions affecting your overseas travel or residence. Consular officers also perform non-emergency services, helping Americans with absentee voting, selective service registration, receiving federal benefits, and filing U.S. tax forms. Consular officers can notarize documents, issue passports, and register American children born abroad. "
I've just registered via the website. I'm wondering if anyone else has done the same, and if anyone has ever had to turn to them, and if they've been helpful at all.
