Not an immigration question.
Behar Intl. Counsel 619.234.5962 Kindly be advised that the answer above is only general in nature cannot be construed as legal advice, given that not enough facts are known. It is your responsibility to retain a lawyer to analyze the facts specific to your particular situation in order to give you specific advice. Specific answers will require cognizance of all pertinent facts about your case. Any answers offered on Avvo are of a general nature only, and are not meant to create an attorney-client relationship.
I don't know anyone who does only petitions for factual innocence. Many attorneys do one from time to time. Winning one is difficult depending on the facts of your case and what the charge was. Scan Avvo attorneys to find one who is regularly in SM County.
Before you do this, make sure that it is strategically sound and properly timed for your specific purposes. There are some matters such as state licensing applications in which filing for an Order re Factual Innocence can actually cause the Petitioner a serious disadvantage, depending on some of the circumstances of the past non-conviction.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
