I am willing to take the Lean Six Sigma green belt exam, but I saw that I am required to have a minimum of 2 years work experience. I am currently a student, is it a mandatory requirement?

Dear Hany

Good evening!
its better to start with yellow belt instead of green

you can go for green belt certification from ASQ when you get 3 yrs exprience 
The Six Sigma Yellow Belt certification is aimed at those new to the world of Six Sigma who have a small role, interest, or need to develop foundational knowledge. Yellow belts can be entry level employees who seek to improve their world or executive champions who require an overview of Six Sigma and define, measure, analyze, improve and control model (DMAIC).

we can help u!
