The documents needed depend on the visa route and your circumstances, but usually include your passport, current immigration documents, application correspondence and evidence of finances, accommodation, employment or family relationships. You may also need proof of English language ability, qualifications, travel history and any previous visa refusals, with certified translations where documents are not in English or Welsh. An immigration lawyer may request further evidence after reviewing your case. Check the relevant visa guidance on GOV.UK and, if taking legal advice, choose a solicitor regulated by the SRA.
