I have a petty theft charge (484 A) on my record from 1989 and a trespass (602 J) from 1993, they have both been expunged and my record has been clean since. I currently hold a green card and would like to apply for citizenship.
I was told by an immigration attorney that there is a legal procedure (the legal term sounded latin and more than one word) that is not used often but can be used in cases where the consequences of pleading guilty are not explained to the defendant. I was told this legal procedure can remove/drop the charges from my records and is different from expungement which still remains.
Does anyone know about such a law? Do you know the legal term? Unfortunately, I lost this attorney's contact information so I would appreciate any help I could get.

It could cost you a fortune to do what that attorney told you. This is not a DUI or felony charge... not worth it.

The best choice for you is to retain a good immigration attorney and focus on good moral character since the last one was in 1993 or over 10 years ago.
