求问EAD寄丢了的话，OPT开始时间可以改么

LZ的EAD卡因为改地址，邮箱没有名字等原因，现在的状态是“card was determined undeliverable by the post office" USCIS让我联系邮局，因为邮件现在不在他们手里，我去问了邮局，说是会回到我的旧地址那边一趟，但我不太确定，因为这些人一个人一个说法。

所以如果做最坏打算，重新申请一次的话，OPT的开始时间可以改么？毕竟这样做的话会白白浪费两三个月

开始时间改了，结束时间还是一样的。。。

关键start date要是不能改的话，如果浪费掉了两三个月，岂不是直接就90天 unemployed 的了。哎，不清楚到底是怎么样的，请问有人有类似经历么？

我只在网上搜到过这样的答案，虽然有点儿老了。。

"Replacement EAD
An application for a replacement EAD is filed if a card has been lost, stolen, or mutilated, or when the previously issued card contains erroneous information, such as a misspelled name or name change. If an application for a replacement EAD is approved, the replacement EAD will have the same dates and category as the EAD that was lost, stolen, etc.
Persons applying for replacement documents can present the receipt for the I-765 as evidence of employment eligibility but must produce a valid card within 90 days of showing the receipt."

我当时寄丢，USCIS 自动把开始时间推迟到新的发卡时间了
