我今天收到 USCIS 发给我岳父岳母的信件，里面写着 「A review of official records shows that you departed the United States on September 28, 2020. Because you have departed the United States, you will be unable to satisfy the biometric requirement of the Form I-539. Regulations require all applicants on a Form I-539 attend a biometric appointment at their nearest ASC. USCIS is denying your application as a matter of discretion. Should you seek to re-enter the United States as a B nonimmigrant, you will be required to establish your admissibility again and be granted admission as a B-2 nonimmigrant by U.S. Customs and Border Protection.」 最后一句话是什么意思呢？签证没有取消，下次能不能入境还是看海关？是这个意思吗？
Having a U.S. visa allows you to travel to a port of entry, airport or land border crossing, and request permission of the Department of Homeland Security (DHS), Customs and Border Protection (CBP) inspector to enter the United States. While having a visa does not guarantee entry to the United States, it does indicate a consular officer at a U.S. Embassy or Consulate abroad has determined you are eligible to seek entry for that specific purpose. DHS/CBP inspectors, guardians of the nation’s borders, are responsible for admission of travelers to the United States, for a specified status and period of time. DHS also has responsibility for immigration matters while you are present in the United States.
移民局拒信里的这句话，「Should you seek to re-enter the United States as a B nonimmigrant, you will be required to establish your admissibility again and be granted admission as a B-2 nonimmigrant by U.S. Customs and Border Protection」，说的就是这个意思：下次你持 B 签证来美国，仍需获得 USCBP 官员批准、拿到 B2 status，方可入境。这句话是模板，适用于所有外国人，可忽略不管它。不只是你，所有 B-2 乘客，以及其他签证的乘客，都需要 USCBP 官员批准方可入境。
