回复：紧急请问各位大侠关于I-485file后的EAD和H4的问题

The important thing is that the CIS never know you used the EAD,(when you start working, you will fill out the I-9 form, however that form is not required to forward to CIS, and only kept by your employer for CIS inspection which barely happened), so in this regard, the lawyer Fan is right that you are still H-4.
