My brother was sent an email from ukvi that his visa and that of his family has been approved. He got a message from TLS to come pick up the passports. But On getting there. He was told that Ukvi asked that his wife’s passport be returned. He was able to collect his passport and that of his kids. It’s bn over a week now. He has not received any email that the passport has bn returned to TLS. Does anyone have an idea of what could be wrong and how long it will take for them to return the passport?
