美國公民入籍申請變慢

USCIS去年初接到入籍申請39萬件，屬正常申請量，平均處理時間約四個月。但去年收到的申請總計逾63萬5000件，其中第四季收到近24萬件，但僅處理11萬2000件，不到收件量的半數。

USCIS表示，入籍積壓是因為申請爆增，導致處理時間加長。但維權組織指出，去年積壓的申請增多64%，但申請量比2015年只增多27%，比大選年的2012年只增14%。

Merit-Based Immigration System

The current U.S. immigration system favors uniting family members with relatives already in the country. It was built on the premise that any person, regardless of how much education or money they have, can come to the United States and create a productive life for themselves.  

However, President Trump is pushing forward with his promise of a harder line on legal immigration, endorsing a proposal to slash the number of immigrants admitted to the United States while favoring those with certain education levels and skills.

White House staff have been working closely with Cotton and Perdue for weeks on the legislation, which would restrict how the U.S. admits immigrants and move to what Trump has described as a "merit-based" system similar to that used in Australia and Canada.
