感谢8老师！关于EAD卡还请解惑！

真的感谢8老师，是的我们又提供了一份RFE要求的材料，附在了290B里。

关于EAD卡renew，我查的是这个网页，链接为http://www.us-immigration.com/blog/how-to-renew-an-employment-authorization-document ，我开始以为是不管什么原因的renew都必须付380元，就如这段文字所说：

Applicants who seek to extend their work permits need to gather the required supporting documents. They need to send photocopies of the previously issued work permits and Form I-797, USCIS approval notice of the permits they hold, along with their applications for renewal. If they have applied for adjustment of status, they need to submit copies of the receipt notices of their pending applications for permanent resident status. Along with these supporting documents, they need to submit two passport style photographs and the form filing fee of $380. Cash must not be sent. A check or a money order must be used to pay the form filing fee.

是不是我对这段话理解的不对？
按您的意思，是不是其他原因的renew需要交380元，但基于485身份调整的，就不需要再付钱了？

实在是有点不放心，害怕如果自己搞错了，再惹来EAD卡的麻烦，那老婆就无法工作了，所以望您再次帮助解惑，感激不尽！！！
