五月底网申initial OPT二次制卡timeline

5/27 Case was received
8/24 Card was being produced （本来以为一个星期内就能收到卡可以按时上班了，结果等啊等状态一直不变，又得知同学有比我晚三天提交申请的在9/4就收到卡了，开始慌了，9/7去戳emma live chat什么都没问出来，只告诉我30 days for a card）
9/8 Card was being produced （看到状态又更新成produced了，去戳emma，这次的客服比较负责，帮我查了一下，说我的在8/27制卡失败了，然后9/8才重新送去制卡。。他也不知道失败的原因是什么，我问我需不需要take any action他说唯一能做的只有等）
9/13 Card was produced
9/14 The Post Office picked up
9/16 Card was delivered to me
