College transfer from Europe

<p>I have a Master's Degree from abroad and am considering going back to college here for some more graduate studies.
Can anyone tell me what a college credit exactly constitutes? Is there such a thing as a national college credit or does it very from school to school.
I got 245 European Credit Transfer Points. How does this translate into US credits? So far I have not been able to find someone to help me, so I.m hoping here I'll find someone....</p>
