Compelling Circumstances EAD
The regulations enacted by the USCIS on 17 January 2017 have created a new class of employment authorization - "Compelling Circumstances EAD." This is available to those people whose I-140 is approved and priority dates are not yet current.
Thanks to Leila for doing a wonderful follow upon RFE for the EAD. I got my EAD approved very soon after an RFE was issued.
