I was refused a UK visitor visa due to an overstay on my Tier 4 visa. I was in the UK on the Tier 4 visa from February 2012 to March 2014, at which time I applied for an extension and stayed in the country.
I was notified in September 2014 that my case had been assigned to an officer. In January, when I had heard nothing further, I asked to withdraw my application and was first told that my documents would be returned to me. Shortly after that, I was told by email that my documents had been lost in the mail.
In April 2015, I received another email saying that UKBA was holding my documents. Again, I asked for them to be returned to me so that I could leave the country. I returned to India on 17th May 2015.
Now they have refused my visit visa, asking what I was doing in the UK between September 2014 to May 2015, after my sponsor's license had been revoked. I left the UK voluntarily and bought my own ticket.
Should apply again for the visit visa, and also attach all the emails I received from UKBA between September 2014 and May 2015?
