Citizenship is decided partly by a test, and the test is narrower than it looks: a known pass mark and a fixed body of material. In the US that is a published list of civics questions, asked at an interview that is as much a test of spoken English as of the answers themselves; in the UK it is a 24-question test set from one official handbook. Pick the country you are applying in: the US track works through the official question banks and rehearses the interview out loud; the UK track works through the handbook's chapters and full mock tests.
In both countries, passing the knowledge test is not the whole of it. In the US the interview also assesses your spoken, read and written English, and each part is scored separately. In the UK the Life in the UK Test does not satisfy the English language requirement: you also need B1 or above, through an approved qualification or a degree taught or researched in English. Sort out the English side early — it is easy to underestimate.
Questions whose answer depends on who currently holds office — the president, your senators, the monarch, the Prime Minister — are kept out of the practice tests, because a fixed answer key would go out of date. The US track gives them their own look-up checklists, one for each version of the civics test, which say where to check each answer; where they show a name, it is the one USCIS listed in September 2026, a starting point rather than an answer to learn by heart. Look those answers up yourself from an official source, close to your test date.
Zestly is an independent study tool. It is not affiliated with USCIS or any US government agency, nor with the Home Office, UK Visas and Immigration or any official test provider, and it is not a test centre. Nothing here is legal or immigration advice: eligibility, exemptions, fees, booking and the conduct of your test or interview are matters for the official authorities, and for an immigration attorney, accredited representative or adviser if you need one.
