My husband also qualifies and wants to apply for the HSMP. We are also looking for a reputable immigration agency to handle the application as I have read that if your application is rejected, you may not apply again. So we don't want to risk applying on our own as we may miss something important. It seems to me that the agency should definitely be authorized by the OISC. I have read on another forum that some people have had good recommendations for Global Visas.

Will keep you posted on any other info I can dig up
