Is clearing USMLE necessary to work as radiologist in USA/Canada ?

[ashgautam]

Hi,
I have MBBS and MD degree in Radiology from India along with couple of years of experience in radiology field while working in India. I am looking for Temporary or Permanent job in Radiology Diagnosis field in United states/Canada.

Here is my question: Can I get job as Radiology Diagnosis Technologist in USA after passing ARRT certification(www.arrt.org) ? Or I have to pass USMLE before I go for ARRT certification ?

And is it possible to get H1 visa for this kind of job ?

thanks for your time,
ashgautam

USMLE is required to practice as a physician in the US. There may be other exam requirements to work as a radiology technician
