A refusal under UK immigration law is an indication by the ECO that the applicant failed or was unable to satisfy the ECO that they fulfilled the relevant immigration rule. The option that may be available to an applicant after a visa refusal may depend on the visa category or type applied for. In almost all cases the applicant will be supplied with a Notice of Refusal setting out the refusal correspondence and the reasons supporting the decision.
For all visit visa categories, an applicant is not entitled to a full right of appeal. They enjoy only what is considered a limited right of appeal under section 84(1) (b) (c) of the Nationality, Immigration and Asylum Act, 2002. A ground of appeal against an immigration decision under this section must be that the decision is unlawful under section 19B of the Race Relations Act 1976 or section 6 of the Human Rights Act 1998. To establish a ground of appeal under the race relations or on human rights ground may in most cases be extremely difficult for a visitor visa applicant.
The only remedy against a refusal of a visit visa therefore is for the applicant to submit a new application with any additional information or documentation. In any case, the provision of additional information or documentation does not in any way guarantee that the application will be successful. The ECO is obliged by law to consider the application as a whole and on its merits.
