"外来人士" 在英语中通常称为 "foreigner" 或 "non-native speaker." 如果你想表达外来人士说的话，你可以使用这些表达方式：

"A foreigner said..."
"A non-native speaker said..."

例如：

"A foreigner said that he was having trouble finding his way around the city."
"A non-native speaker asked if there was a store nearby that sold souvenirs."

希望这能帮到你！
