I am trying to find out if the on line Belford High School Diploma is ligitimate and if they are really registered with UCOEA as they say they are? They are located in Humble,Texas but that is as far as I can get?

I'm 18yrs. Old from japan and wants to go to college in New York usa. I got high school diploma on line from belford high school . Is it possible to use this diploma as one of the requirements in entering college in New York,usa?

How long do I'll wait for the exact answer to my question?
