That's a tricky one. If you are doin' a specialty then one can always say that you intend to go back to home country and stuff like that.
But when it comes to dds, i guess if they figure out that
- it gives the applicant a chance to get a license to practice
-and that one is enrolling in the same degree course which had been completed earlier ...shall put one in a 50-50 situation.
I think just tell them that it is a program for foreign-trained dentists to enhance their skills to US standards and that you wish to return back after gaining little experience.
Wait for other people's response to get the first hand information though!
