Thanks leorl for your reply.
So wat i can understand is that there is no internship in U.S. for the graduation degree,there is only a four year curriculum.....
Actually i wanted to know that when clerkship programs have the criteria for imgs as "International students must be within one year of their graduation and receipt of their medical degree ",.... they are referring to internship, right? like at my place we receive our degrees in march so till then anytime can we apply to these programs?
