“非法入境者”常见的英文表达是 “illegal entrant” 或 “illegal immigrant”(不过“illegal immigrant”更侧重于指已非法入境并停留的人,而“illegal entrant”更直接对应“非法入境者”这一行为动作的当下主体)。此外, “unauthorized entrant” 也是一种较为正式且准确的表达,强调未经授权的入境行为。
例句:
The authorities are cracking down on illegal entrants.(当局正在严厉打击非法入境者。)
Security measures have been strengthened to prevent unauthorized entrants.(安全措施已得到加强,以防止未经授权的入境者。)
