Rice- When I first started dancing, I learned American first. At that time - 11 yrs ago, one didn't start Int'l style until Amer. Bronze completion and into Silver - with some exceptions. A few reasons could be: 1)one should be well rounded in "social" dancing, to be comfortable in a social setting- a dance, wedding, etc. 2)Int'l style is more "competitive" like Silver Amer. and above - more technical, some continuity, slower (or faster) tempi depending on dance, etc. I dance and compete in both styles, and enjoy them both, but I feel that one should start with a social background, and if interesred in competition, learn Int'l along with American, as different as they are, they can also be similar. Learning/competing in both styles improves the quality of one's dancing, and makes one more knowledgable. I hope that my opinion has helped you. Good luck in your dancing. Len
