You can make an InfoPass appointment or hire an attorney if you wish. Please see
Mr. Shusterman's (former INS Trial Attorney, 1976-82) response to your question is general in nature, as not all the facts are known to him. You should retain an attorney experienced in immigration law to review all the facts in your case in order to receive advice specific to your case. Mr. Shusterman's statement above does not create an attorney/client relationship.
It very well could be. Did you file a change of address within 10 days of moving as you were supposed to?
Gunda J. Brost Brost Law Office This advice does not form an attorney-client relationship and is merely informative. It should not by itself be relied upon to address a legal concern.
Moving without updating your address with the USCIS could be one of the reasons. I would highly recommend you to hire an immigration attorney at this point.
