EAD "serves as I-512 Advance parole"是真的？

皮老师您好：

    上周收到了EAD，卡的最下面写着“serves as I-512 Advance parole”。因为两周后要回国，感觉像天上掉了馅饼一样。想再请皮老师帮忙确认一下：

    下面是我在USCIS上查到的：Why did USCIS combine these benefits in one card?
A2.  With the new card, adjustment of status applicants no longer will have to carry both an EAD and a separate paper Advance Parole document while awaiting adjudication of their Form I-485 applications. Instead, applicants only will have to carry this one credit card-sized card.  The new card is more secure and more durable than the current paper Advance Parole document.

非常感谢！

Best always,
