回复：再问各位老师关于EAD有效期

听说EAD有效期是二年了。但是我日前收到的卡上有效期还是1年。是不是因为我是第一次申请所以有效期是1年，以后再申请就会是二年了？
-You are qualified for the two-year EAD.

如果是USCIS的错误，我打算写信去，但我在USCIS的网站上找不到相关的规定
-Yes, it is USCIS 的错误. If you want to request USCIS to correct it (send you a 2-year EAD), just write a letter to describe the nature of the error as clearly as possible and also submit the incorrect EAD card with this letter to the address where your EAD was issued. Please remember that if you use EAD to work, you need to show your one-year EAD card to your employer (your employer makes a copy of it) so that you can continue your work before you return this card back to USCIS.
