Say, for example, I had a student visa that allowed me to stay in America from September to February. Would I then be able to come in August on a Visa Waiver to America, and then when September comes around, would it then just switch over automatically to my student visa as I begin my school, without leaving the country?
Or would I have to leave the country and then come back to begin my stay as approved by my student visa? I would like to visit some family before I start school, but don't know if I am able to use the Visa Waiver for that stay.
