Hi, I recently came to live to NYC I'm legal and I have a valid work permit,I was a kindergarden teacher in my natal country, Mexico,i have 15 years of expirience,i'm bilingual, english/spanish, I have all my school , certificates and recomendations, translated to englis by a consular certified translator from , Mexico, I have a B.A. in preschool education. How can I certify my studies in NYC and were is the board of education?

So here's the deal: During my undergraduate I took several sociology classes: Intro, Social Problems, Social Stratification, Social Statistics, and Anthropology. I ended up getting my undergraduate degree in Human Resources, and I have gone on after taking a year off school to begin work on a Masters of Education in Adult and Higher Ed (right now I have a 4.0). My GRE scores are not that great (average), but I did get a 4.5 in Writing. I think my research interests lie in the realm of Social Psychology/Sexuality/Gender related issues, and sociology might be a better fit for me. What are my chances of getting into a sociology PhD program? How much would it help me to take Graduate level courses in Classical Theory, Methods, and Stats before I apply? Is it necessary? What am I looking at here as far as deficiencies? Any advice would be great! Thank you!
