Yes, you have to go to an accelerated program or start over if you do not have a 5-year or greater degree. The 5-year or greater degree allows you to take the FPGEE (which is the foreign equivalency exam).
You apply to Nova and Western. There are some other international programs out there as well. But those are the first two that come to mind.
If you do not get in to the accerlated program, then you have to start over unfortunately.
