Immigration inspectors have discovered more UK Border Agency (UKBA) backlogs totalling over 16,000 cases.
The chief inspector of immigration said the latest backlogs relating to requests to settle through marriage were "unacceptable".
The backlogs included people waiting a decade to hear if their partner had permission to live in the UK.
The Home Office said the UKBA was already taking action to deal with historic backlogs.
