What happens if I am arrested on a US provisional warrant before the formal extradition request arrives?

The US has 65 days from your arrest to submit full extradition papers to the UK authorities. During this period, you will be remanded in custody unless bail is granted — which Westminster Magistrates’ Court approaches cautiously in US cases given flight risk concerns. If the formal request does not arrive within 65 days, you must be discharged, though re-arrest remains possible if papers are later submitted. This window is critical for preparing your defence, gathering evidence for bail applications, and identifying preliminary challenges to the request.
