Just about 1 year short in long time residency, plz advice

Hi evryone. seeking advice .
came in UK in march 2006, on student visa. between 2008 to 2010 had a PSW visa.after that done MBA IN FINANCE WITH 69% result.currently on student visa until march 2015, studying CIMA which i will not be able to finish its last semester due to its changes in course. current t-4 finishes in march 2015 .ALSO having a child who is born in UK in 2008 . please advice me to bridge this gap.
thanks in advance.

Is the child a British Citizen?

What is the immigration status of your partner?

No, child and a partner are my dependent .

So the child is not British, otherwise that could have been a route. How old is the child?

The only option you seem to have is to find another visa that you qualify for (Tier 2 or any other PBS visa).

current T-4 expiring in march-15. maximum time as a student is finishes... shalll i go for PH.D or any other option? child age will be 7years in december 2015.
