Can two children aged 15 stay in an American hotel alone?

I can't. The passport inspection of American hotels is very strict, and the legal requirement is 2 1 year. Two 15 children did not meet the legal requirements and could not live alone, so they needed to be accompanied by qualified people. If two 15 children go to America alone, they must pay attention to their own safety, try to act during the day, and don't act alone after dark.
