the scope for students who have done BDS in India & want to apply abroad(USA) for further studies

<p>Hey everyone i have heard people say a lot of things about going abroad after doing BDS in india. We have to clear NBDE ? is it tough? and do we have to again attend dental college for 2 years?
IN A NUTSHELL i want to know if i do BDS in India and at the end if i want to settle in USA and practice as a dentist What are my chances?
Thank You.</p>
