Career switch from business to statistics

I am a business undergrad with marketing major from a South Asian country. I want to switch my career to statistics. I have done only Stat 1, Stat 2 and Math 1, Math 2(covering Optimization, Calculus 1).Can you please suggest me how should I proceed if I want to do Stat masters in USA/Canadaian program? If I do a masters here then apply would that be okay to compensate for my lack of enough background?
Are you a US or Canadian citizen? I mean an obvious start would be to find out what the requirements of the program are in terms of being admited and prerequisites which are in university bulletins or admissions documents.

Ultimately only by talking to the department you want to go to can you get an answer to this. There simply is too many variations in US universities.
