You can visit someone who was sentenced to life in prison.
As long as the prisoner or inmate has placed you on their visitor list and you've been approved by the prison to visit the inmate you can visit the prisoner no matter how long their sentence is including life in prison.
You can only visit the prisoner on visitor days and visiting hours.
All incarcerated people are eligible to receive visits unless they have temporarily lost that privilege due to disciplinary action.
Death-sentenced or death row prisoners are also permitted semi-contact visits with family and friends on their visitation list, and confidential non-barrier visits with their attorney of record during their incarceration.
Any sentence without parole effectively means a sentence cannot be suspended; a life sentence without parole therefore means that in the absence of extraordinary circumstances such as pardon, amnesty or humanitarian grounds (e.g. imminent death), the prisoner will certainly spend the rest of his or her life in prison.
Each prison facility has its own visiting days/hours, so check with the inmate you want to visit to determine what day or days you will be able to see them.
Generally, prison visits are available on Saturdays, Sundays, and holidays, although individual facilities may limit visits to just one day/week.
For prisoners in state custody, the availability of conjugal visits is governed by the law of the particular state.
The four states that currently allow conjugal visits are California, Connecticut, New York, and Washington.
