You can check employment listings to see what qualifications are needed. They do a background check and your past may have caught up with you in that regard. The one listing I saw said that 15 years must elapse and you must not be on probation.
A felon would generally be ineligible for such a position. In most cases he could overcome the ineligibility by returning to the court where he was convicted and seeking "relief from civil disabilities" which is something that a judge may choose to grant after a period of law abidance post-conviction. However, even with such a certificate, a felon will tend to have a difficult time obtaining any white collar (e.g. "office") or other professional employment. It's not necessarily inconceivable for a felon to become a police officer, especially where the criminal record is relatively limited and includes only non-violent crimes not involving dishonesty. Skilled blue collar trades (e.g. plumber, electrician) are popular with felons since opportunities in these trades do tend to be open to felons and offer decent pay and benefits, however again individual state licensing issues and prohibitions against felons should be consulted. Check with a union apprenticeship program which will offer paid training and steady work thereafter.
I know in Washington state you can, I knew a fellow who was a Deputy who had a bunch of Juvenile Convictions.
No, not all types of felonies make you ineligible to become a police officer. Most juvenile offenses cannot be carried over to stand in the way of a person pursuing a career in law enforcement. You can also choose to have a crime expunged from your record and would then be eligible to pursue this type of career as well.
it depends whether the immigrant has committed felonies
To put it simply, no, they would never hire you.
You certainly can. If the record was destroyed because of it being a juvenile conviction, you'd be perfectly fine.
It can depend on what the juvenile arrest was for. For a felony crime? Probably not.
absolutely not.
It's not impossible to become a police officer with a juvenile criminal record, but it will be very difficult, especially while you're in your 20s. You will need to show that the juvenile offense was the result of behavior you have abandoned and you have maintained a clean record of good conduct for many years since. This means no arrests, no traffic violations, a good work record, no use of illegal drugs, and meeting all of your financial obligations.
