American prison, explained for the UK.
If you, or someone you love, is heading toward a United States federal prison, most of what you have heard is probably wrong.
The federal system in one minute
"Prison" in America means two systems. State prisons hold people convicted under state law. The federal system, run by the Bureau of Prisons, holds people convicted of federal offences. Fraud, money laundering, sanctions and FCPA cases, securities offences. If you are extradited from the UK, or charged over conduct that crossed borders, you are in the federal system.
Institutions come in security levels. Penitentiaries, medium and low security FCIs, and minimum-security camps. Where you go is not a judge's decision. It is scored, mostly from your presentence report, on custody points and public safety factors. Non-violent first offenders usually score to a camp or a low.
There is no parole. Good conduct time and earned credits come off the back of the sentence, but the number the judge announces is close to the number you serve.
Day one
You arrive with almost nothing. The first hours are processing, a phone list, and a commissary account your family funds from outside.
The unwritten rules matter more than the written ones. Mind your own business. Do not gamble, do not borrow, do not discuss your case. Be polite to everyone. Most trouble new arrivals find comes from carrying British prison assumptions into an American yard.
Staying in touch runs through Corrlinks email and debit-account phones, both expensive from the UK. Visits need approval and planning. The charity Prisoners Abroad supports British nationals imprisoned in the US and is worth contacting early.
US v UK, the four differences that decide how you prepare
Plea bargains are the system
More than 95 per cent of federal cases end in a plea. The gap between a plea offer and a sentence after trial, the trial penalty, drives everything. Britain has nothing on this scale.
Sentences are arithmetic
The Sentencing Guidelines score the offence and your history into a range measured in months. Mitigation in the British sense matters far less than the facts that feed the arithmetic.
No parole exists
Good conduct time takes roughly 15 per cent off. First Step Act credits and RDAP take more, for those who earn them. Nobody comes home early on licence the way they do in Britain.
Dormitories, not cells
Camps and lows house people in open dorms or two-person cubes. Headphones are the walls. Privacy as a British prison knows it does not exist.
The facilities people ask about
Nine institutions that come up constantly with UK clients. Camp populations are from the Bureau of Prisons roster of 30 July 2026. Current status always lives on the BOP page.

Questions people in the UK actually ask
Can a UK citizen be sent to an American prison?
Yes. Extradition to the United States, or charges over conduct in US jurisdiction, end in a sentence served in an American institution. Most British defendants in white-collar and fraud cases are designated to minimum-security camps or low-security facilities.
Is there parole in the US federal system?
No. Parole was abolished for federal offences committed after 1987. The sentence announced in court, less good conduct time of about 15 per cent and any earned credits, is close to what will be served.
Can you transfer to a British prison?
The treaty transfer scheme exists, but approval is rare and it takes years. Preparing for the American system is the realistic plan.
Will you be safe?
The camps and lows where non-violent, first-time defendants go are, by prison standards, calm. There are written rules and unwritten ones, and the unwritten ones matter more.
