A felon can get a passport as long as the felon is not considered dangerous and has no other criminal history.
Being a convicted felon does not bar someone or prevent someone from getting a passport to go to other countries.
As long as the felon is allowed to leave the country then they can get a passport and travel to other countries.
Now if the person is on probation and cannot leave the country or state they are in then they cannot get a passport to leave the country.
But you certainly can get a passport even when you're a felon.
However having a felony conviction can prevent you from getting some jobs but even with a felony conviction you can find a job if you look hard enough.
Some employers are willing to give a person a second chance.
