Can apply anytime. An expungement is worthless if obtained for immigration purposes. Yours is not a CMT, you thus have nothing to worry about,
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.
Expungement does nothing, USCIS and ICE will see your record when you do the biometrics. You will need to explain the arrests and convictions, with your crim file destroyed - not an easy task, I would not advise you to expunge the record until you naturalize.
I do not see what could push or trigger USCIS to review your crim record while reviewing the H-1b. However, it will be an issue if you decide to apply for the LPR status.
I agree that simple assault is almost always not CIMT.
Apply for your H-1B anytime you want. This doesn't sound like a CMT. Expungement won't help you.
