International entry to UK accountancy is by visa plus skills, and cross-recognition is body-to-body, not a single conversion. The US CPA is licensed state-by-state (state boards / NASBA, with AICPA setting exams), and there is no automatic UK-US reciprocity for individuals. A long-running ICAS/ICAEW-AICPA mutual-recognition pilot was suspended or allowed to lapse (described as “suspended, not ended” in 2025), so a US CPA wanting ICAEW or ICAS membership currently routes through that body’s “members of other bodies” assessment or exams — not an automatic swap. Do not assert a live US-UK mutual-recognition agreement. There is no medicine-style “convert your licence” route; keep the international section short and lead with the UK structure.

- There is no automatic US-UK reciprocity for individual accountants; a US CPA seeking ICAEW (or ICAS) membership routes through the body's "members of other bodies" assessment route rather than an automatic swap — source, verified 2026-06-12
- There is no current US-UK mutual-recognition agreement for accountants: the AICPA (US CPA) does not appear on ICAEW's list of mutual-recognition agreements, so a US CPA has no automatic route to the UK ACA, and vice versa. — source, verified 2026-06-12
