The Immigration Service should mail you all correspondence too despite having an attorney unless the attorney represent an employer through whom you apply.
Generally speaking USCIS will send everything your attorney receives to you as well. If that firm no longer represents you, tell them to notify USCIS of that or you can write a letter to USCIS stating that the attorneys no longer represent you and to send all correspondence directly to you. As far as USCIS is concerned since the attorneys most likely filed G-28 Notice of Representation they will send it to them unless notified otherwise. Good Luck!
I agree with my colleagues.
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.
Write directly to USCIS informing them that the law firm is no longer representing you and to send all future correspondence to you.
