特朗普总统因打击非法移民而受到关注，但他在限制合法移民方面也同样强硬。他政府在今年早些时候通过阻止来自全球近一半国家的移民签证的政策，使合法移民人数减半。
President Trump has drawn attention for his crackdown on illegal immigration, but he has also been tough when it comes to limiting legal immigration. His administration cut legal immigration in half early this year with policies blocking visas for immigrants from nearly half the globe.
签证冻结使得来自数十个国家的移民几乎变得不可能。学生签证和工作签证也出现下降。
A freeze on visas made it all but impossible to immigrate from dozens of countries. Student and work visas also declined.
