回复：网上EFILE EAD后

是等USCIS的RFE再寄补充材料, 还是就直接寄补充材料给他们? 想要他们处理的快一点.
-You need to send the support documents by mail for your efile EAD application immediately after you efile the application. Print a copy of your Confirmation Receipt notice and attach it as a cover page (or first page) to your supporting documentation package.
