Just want to share my experience with you. My visa was cancelled by my previous employer. Luckily, I was given NOC due to some technicality. Nwei, my current sponsor applied for visit and business visa because they told me that I don't need an NOC not until I will transfer my visa into working/RP. But it was denied by the immigration because I was cancelled by my sponsor. So they submit again with my NOC attached for the business visa application w/c was approved immediately.

But according to our PRO, if it was not cancelled they can transfer my visa even without NOC. That is according to his "contact" in the immigration.

Goodluck...
