Applied Family Visit Visa in 2018. Refused after 3 weeks. Complained against the decision within 1 week.After 3 weeks were asked to submit further documents on email and then resubmit passport and got the passport back after further 2 weeks. Application to Refusal to Complaint and Approval all within complete 2 months.
The complaint procedure is listed on the following GOV.UK page https://www.gov.uk/government/organisations/uk-visas-and-immigration/about/complaints-procedure and at the same time the sponsor or relative in UK can complain to their respective MP. Following both steps at the same time gave us a favourable result.
