Generally speaking, when you are adjudicated guilty of any crime, misdemeanor or felony, it stays on your record forever, unless you can have it sealed or expunged. To do this you must apply to the state or federal Government for such.
You will have to contact your military recruiter for the final answer. I suspect that if there is no record of a conviction, you will make it.
If you were convicted of a felony, it will be almost impossible to remove from your record-unless there was a major mistake on the court's part.
This depends on the exact charges brought, and the prior record of the person charged.
Not knowing the nature of the offense or the state in which it occurred a specific answer is not possible. In all states most juvenile adjudications (including minor in possession) remain confidential and are sealed when said person reaches the state's legal age of majority. In California, if you are convicted of an infraction for minor in possession, rather than a misdemeanor, it never makes it onto your "record" in the first place.
With a record like that, if he is convicted of the gun possession charge, there is an excellent likliehood that he will be imprisoned for a LONG time.
This depends on the exact charges brought, and the prior record of the person charged.
No. "Convicted felon in possession of a firearm" is a violation of FEDERAL law (US Code, Title 18) and an expungement in OH has no bearing on your status. (Your criminal history record is always accessible to government agencies.)
It's impossible for convicted capital murder to have that record expunged.
Not unless they return to New Jersey to petition the NJ Courts to expunge their record. Your record can only be expunged by the jurisdiction in which you were originally convicted. Your felony conviction follows you for life and the penalties for violating the firearm possession laws are HARSH.
Generally speaking, no. However, you say "charge", not "conviction". If you were not convicted of the drug charge, you can go to the Court and file a motion to have the record expunged (destroyed). If you get your record expunged, it is like it never existed, and you can work in the Crim Justice field.
If the abuser was tried and convicted of a felony such as assault, then yes, it will show up in a criminal record. If never convicted, then no.
Once convicted a misdemeanor takes effect immediately. Even before a person is convicted of a misdemeanor crime it can be viewed on a persons record as pending.
