Good Luck.

Requirements are:
A four-year Bachelor's degree from an accredited US institution or its international equivalent.
A minimum of two-three years of work experience, depending on your responsibilities.
Resume
Personal Statement
Two letters of professional recommendation.
Proof of English proficiency (TOEFL is the most common requirement- minimum scores: paper-based: 550-=600 and computer-based 213-250).
GMAT score of over 600 (probably the most important thing).

You can do MS from USA from some renowned college. This will give a new and bright direction to your career.

You don't need to appear for GRE unless you are planning for MS in the US. What matters the most is GMAT. However, as far I know there is no exemption as such in US universities for GMAT which Means you must need to score good marks in GMAT (it actually differs for every university). Additionally, you also need to have a good band score in IELTS or TOEFL (if the medium of instruction in your last attended university is not English).
Hope this helps.
Good luck.
