但在美国国务院关于放弃国籍的网页上载明,根据美国“移民及国籍法”(Immigration and Nationality Act)条文,要放弃美国公民身份的人需向美国海外服务处的领事官员提出必要文件,由在美国华盛顿的国务院决定是否批准。
网页资料并指出,除非直到美国国务院批准这份“放弃国籍文件”,否则仅有宣誓也是没有终止美国公民身份的法律效力的(unless and until a certificate of loss of nationality is approved by the U.S. Department of State, the oath of renunciation, even though signed by the individual is not/not legally effective in terminating the person's U.S. citizenship)。
