Hello again,
After 5 months of waiting, were you able to receive any certificate from the province stating that you are nominated? If you have not received any then it still a long process you have to wait.
The nomination certificate that is being given by the province of Manitoba does not constitute your permanent resident visa. The visa will still rest in the decision of the Federal government, which is through the visa immigration officer.
The good news is that, history is on your side. There are great percentage of people that were nominated by a province are able to receive their visa afterwards.
All you have to do is wait and hope for the best.
Goodluck lad.
