It would appear that an interfile request is the next logical step for you, and you would be well served to consult with an attorney who has experience in this area. If you do not consult with an attorney, you should at least seek guidance from the USCIS web site (www.uscis.gov).
I agree with my colleague.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
