It's interesting, but I did a similar research about working in about 3-4 countries, but I settled 4 months ago in Denver. I'm a licensed professional counselor, and my work is obviously often intertwined with social work.
I think the place for you to start is to find out if your education would be recognized in the US, and the best would be to have some licensing board give you equivalents for it. A nationally recognized organization that credits the best programs in the country, is CACREP, and that would be a good starting place for someone interested in counseling accreditation:
Another option would be to see if a university would accept your studies, and this way get some certificate in the US, thus having an American degree which would give you more credibility and chances for work here. I have to warn you though, the competition is stiff, because there are lots of graduates coming out of lots of universities.
These some thoughts,I hope it helps you some.
