UK Visa Document Checklist: What UKVI Expects From Your Application

UK Visas and Immigration assesses applications on the balance of probabilities. That means your UK visa document checklist is not a formality — it is the entire evidence base an entry clearance officer uses to decide whether your stated plans are credible. STANDARD VISITOR VISA: MANDATORY DOCUMENTS 1. Current passport with at least one blank page, plus previous passports showing travel history. 2. Proof of accommodation and travel plans. Bookings or an invitation letter with your host's immigration status and address. 3. Financial evidence. Six months of bank statements, official and continuous, showing income sources and a balance that comfortably covers the trip. 4. Employment evidence. Employer letter stating role, salary, length of service and approved leave dates. Self-employed applicants add business registration and tax returns. 5. Proof of ties to your home country: property, dependants, ongoing study or an employment contract. 6. Sponsorship evidence if someone else is paying: their bank statements, their letter of support, and proof of their relationship to you. 7. Certified translations of any document not in English or Welsh, with translator details and date. STUDENT AND WORK ROUTES Student route applicants add a CAS reference number from a licensed sponsor, qualifications listed on the CAS, English language evidence (usually a SELT), and maintenance funds held for 28 consecutive days ending no more than 31 days before applying. Work routes add a Certificate of Sponsorship, evidence that the salary meets the going rate for the occupation code, and maintenance funds unless your sponsor certifies them. THE 28-DAY MAINTENANCE RULE This is the single most common technical refusal in UK applications. Funds must remain at or above the required level for 28 consecutive days. One dip below the threshold on one day resets the clock. Print statements that clearly show the closing balance on every day of that window. WHAT MAKES UKVI DOUBT AN APPLICATION - Bank statements that are screenshots or unstamped printouts rather than official documents. - Unexplained deposits shortly before applying. - An employer letter with no contact details an officer can verify. - Travel history that contradicts the stated purpose of the trip. - A previous refusal by any country that was not disclosed. Non-disclosure is treated as deception and carries a re-entry ban. FORMAT RULES THAT CAUSE AVOIDABLE PROBLEMS Upload documents as clear, complete scans. Every page of a multi-page statement, in order. No cropped edges, no mobile photos at an angle, no password-protected PDFs. UKVI will not chase you for a readable copy — an unreadable document is simply an absent document. TIMELINE AND FEES Apply up to three months before travel. Standard visitor processing is typically three weeks from your biometric appointment; priority and super priority services shorten this where available. Book the biometric appointment as soon as you pay, since appointment availability is usually the bottleneck. FINAL PASS BEFORE SUBMITTING Go through your checklist and ask, for each claim you make, which specific document proves it. Anything unproven either needs evidence or should not be claimed. DocuScore AI checks your uploaded documents against the UK route requirements and returns a readiness score with the exact gaps to fix before you submit.
