여권 잃어버려서 벤쿠버에 stranded된 dual citizen

미국 정부 웹사이트 (dual nationality 해외 여행 관련 규정)에서는 미국적자 (이중국적자 포함) 은 미국 출입국 시 반드시 (must) 미국 여권을 사용해야 한다는 규정이 나오네요.

U.S. nationals, including dual nationals, must use a U.S. passport to enter and leave the United States. Dual nationals may also be required by the foreign country to use its passport to enter and leave that country. Use of the foreign passport to travel to or from a country other than the United States is not inconsistent with U.S. law.
