Even being an illegal immigrant didn't really hurt your chances until Trump in 2025. Until this year, you could just make sad noises at an immigration hearing, get your status normalized, then wait five years and get citizenship.
The only crimes that really killed your chances are violent felonies, high-dollar fraud (particularly against the government), and DUIs.
