Immigration Application Evidence Checklist

Immigration applications are decided on documents, and missing or incorrect evidence is one of the most common reasons for refusal — often on applications that would otherwise have succeeded. Fees are rarely refunded when an application fails, so a preventable gap can cost thousands as well as months of delay. Several items also depend on other people or on documents that expire, so they need starting well ahead. Use this checklist to assemble everything before you open the application form.

Give yourself two to three months

The application form is the quick part. What takes time is everything attached to it: certified translations, an English language test at an approved centre, a tuberculosis test where required, bank statements covering a specified continuous period, and letters from employers or landlords who work to their own timescales. Start by reading the specific document requirements for your route on GOV.UK, because they are prescriptive — a bank statement missing a page, or covering the wrong period, is treated as absent rather than imperfect.

  • Check formats: documents in another language generally need a certified translation, and originals or specified formats may be required.
  • Check dates: financial evidence usually has to cover a defined period ending shortly before the application, so gathering it too early is as bad as too late.
  • Check consistency: names, dates and addresses should match across every document. Explain any discrepancy in a covering letter rather than leaving the caseworker to guess.

The consequence of a gap is rarely a request to supply it. Caseworkers can ask for missing evidence but are not obliged to, so most refusals for incomplete evidence are simply refusals — with the fee gone and the health surcharge to reclaim separately.

Keep a complete copy of everything you submit, including the completed form. If a decision has to be challenged, that bundle is where the challenge starts.

Frequently asked questions

What happens if my application is refused?
The refusal letter sets out the reasons and whether you have a right of appeal, a right to administrative review, or neither. Administrative review addresses caseworker errors rather than new evidence, so it suits a refusal based on a misreading of what you sent. Where the problem was genuinely missing evidence, a fresh application with the gap filled is often quicker and more likely to succeed. Deadlines are short and unforgiving, so take advice from an OISC-regulated adviser immediately rather than waiting.
Can I travel while my application is being decided?
Generally not if you applied from inside the UK. Leaving the country while an in-country application is pending is usually treated as withdrawing it, and your passport may in any case be held during processing. If you must travel for a genuine emergency, contact the Home Office about the process for returning documents and take advice first. Plan applications around any travel you already have booked, and avoid applying immediately before a trip you cannot move.
Do I need a solicitor or immigration adviser?
Not for every application — many straightforward cases are made successfully without one. Advice is worth paying for where there is any complication: a previous refusal, gaps in lawful residence, a criminal record, a complex financial position, or a relationship that is hard to evidence. Only use advisers regulated by the OISC or a legal regulator; unregulated advice is both risky and unlawful to provide. Check the register before paying anyone.
How long will a decision take?
Published processing times vary by route and by whether you applied inside or outside the UK, and priority services can shorten the wait for an additional fee. Treat published times as indicative rather than guaranteed, and do not make irreversible plans — resigning a job, giving notice on a tenancy, booking flights — around them. If your application is still outstanding well beyond the published service standard, you can chase it, and an adviser can escalate where the delay is causing real hardship.

Family Visa: Overview

The UK's family immigration rules allow certain close family members of British citizens and those with settled or pre-settled status in the UK to apply to join them. The most common route is the spouse and partner visa, but other routes exist for children, parents, and other dependent relatives. Family visa rules changed significantly in April 2024, with a substantial increase to the minimum income requirement.
