I am woking here in canada for almost 3 years as Health Care Aide and my job category has no possible way to get a Permanent residency. I have a friend that want to hire me as a live-in care giver. Can I possibly change my program? They said that the processing should be outside Canada, if ever I will process my papers to buffalo office, do i still have to get a US visitors visa to submit there or can I just send my application to Buffalo Office. pls help...thanks
