Well you know I am also planning to change my course, I might change it into 1 YR master certificate.
Its more convenient since its a master course its fulfilling the requirements of SNIP, also you can continue one more year to complete your full 2Yr Master degree.
So my point is after completing one Yr master course we can easily apply for SNIP and then continue one more year if we want, so its pretty convenient.
But last time I check from admission department they are not accepting international students in master certificate courses so that why I opted for Master Degree, but I am planning to retry once I am in UoR.
By the way please explain, how you put your case. E.G bank statement, academics and stuff.
