In January 2016, a friend submitted an application for a UK Tier 2 visa. The first response from the Home Office indicated that the case was complicated, in response to an inquiry sent via a solicitor. The second response from the Home Office in October 2016 indicated that a decision would be communicated in 6-8 weeks.
As of January 2017, there is still nothing further, although the applicant has made inquiries via an MP.
Why would it take so long and what can one do?
