On Wednesday 28 October the FCDO published new guidance, "Arrested or in prison in the USA". The page lists its change history as first published. It is a general guide for British nationals, not a change in US law, and it does not say why it appeared now.
What the guidance says
The embassy and consulates cannot get a person out of prison or secure special treatment because they are British. The guidance lists contacts at nine US posts (Washington DC, Atlanta, Boston, Chicago, Houston, Los Angeles, Miami, New York and San Francisco) and the FCDO in London.
The rights it lists are to remain silent, to appoint a defence lawyer or use a public defender, and to have the British Embassy or consulate made aware of the arrest. It also advises against signing any document you do not understand. It covers booking (search, photograph, fingerprints and sometimes a DNA swab), storage of property, prison visits and how to complain about mistreatment. Family members must usually be on an approved list to visit, and a consular visit does not count toward visit limits.
Timelines
The guidance says speedy trial rights typically require the prosecutor to decide within 72 hours which charges to file, and that many states follow that limit; the time varies by state. A first appearance comes within about 2 days of arrest, and arraignment commonly follows 2 to 6 weeks after arrest. If a person is charged and bail is not posted, detention can continue until the trial ends. The guidance says it is not unusual for serious cases to take more than 18 months, and that about 90 per cent of US criminal cases end in a plea bargain.
Immigration holds and bail
If another state, county or agency, including US Immigration and Customs Enforcement, places a hold or detainer, the person probably will not be released even if full bail is paid. The embassy or consulate cannot transfer bail funds. Bond agents often charge 10 per cent of the bail amount, and US arrest warrants do not expire.
What is not in the record
The guidance does not mention firearms, close protection, armed security, work visas or business travel. We searched the full text and found no reference to firearms or weapons. The FCDO's USA travel advice page was not opened for any related change in this run.
What it means for travelling teams
This is Ops Con's reading, not FCDO guidance.
Teams moving principals through US cities can use the page as a public baseline for a pre agreed detention plan. Decide in advance who calls the consulate, which lawyer is retained and who holds that contact, and who speaks to the principal's family and employer. Brief every team member on the points the page makes about silence and about documents. The immigration detainer point is the one to plan around: for a non US national, paying bail may not secure release. Anything involving firearms or armed work in the US is outside this guidance and needs specialist US legal advice before travel.
