based on your request, we researched the status of this case. Your case is currently on hold, awaiting further instruction from headquarters regarding this type of case. The I-485 Asylum supervisor was contacted for further information regarding the hold location for this case. This case has been placed on a “Nunc Pro Tunc” hold shelf, due to the fact that you are not currently eligible for the benefit sought. If this application were adjudicated at this time, it would be denied. Therefore, we are holding your case along with other similar cases, awaiting a headquarters’ determination regarding the application of Nunc Pro Tunc.
Unfortunately, a time frame for cases being held in this location has not been provided. If you have not received a decision or other notice of action on this case within 6 months, from the date of this response, please feel free to contact us again for further updates. We apologize for any inconvenience this may cause.
