Start by checking the relevant visa route and the latest requirements on GOV.UK, as fees, eligibility rules and supporting documents can change. A regulated immigration adviser or solicitor regulated by the SRA can help you choose the appropriate route, prepare evidence and identify potential problems, but cannot guarantee a successful decision. Check an adviser’s credentials and fees before instructing them, and be cautious of anyone promising a visa or fast-track outcome. You will normally need to complete the online application, provide biometrics and meet any English-language or financial requirements that apply to your circumstances.
