今天收到USCIS的OPT I-675 application approval.里面就是讲employment
authorization has been approved.
尤其第二段更奇怪，写的是：
“This card authorizes your employment in the United States. Show this card
to your employer to verify authorization to work during the dates on the
card.”
整封信里面就是这张Approval notice,里面并没有卡（employment authorization
card）.是否他们会另外分开寄，还是他们失误忘记把卡寄给我了。可以直接打电话给
客服问吗？
谢谢大家！
