study level changes (from master level to college level), study permit extension

[roadtofreedom16]

Hi guys,

i intend to study another program right after my current program which finishes in September,
however, the level of the new program (college level, engineering) is lower than the current one (business master),
how's the chance of getting the new study permit?

can anyone who had similar experience or knows cases like this provide some comments?

thanks very much.
