I have filed my I - 485 in December 2011, and received my EAD on feb 2012 and which will expire in February 2013. I plan to file for renewal now.
Do I have to pay $380 renewal fee or since I filed my I-485 after 2007 it is free?
If you paid $1070 filing fee for your I-485 and filed your I-765 concurrently with your I-485, then you do not need to pay the filing fee to renew your EAD. You should file the I-765 between 120 and 90 days prior to the expiration of your current EAD.
I agree with my colleagues.
