Transferring after Sophomore Year

My parents have told me that the only way that I can go to an out of state school is if I stay in state for two years then transfer. Most likely I would start as a Applied Physics major or another discipline of engineering then transfer to a school that has aerospace engineering. I would like to hear from you guys an out your exprience transferring and whether it was more difficult to transfer into an engineering than getting accepted into an engineering program straight out of high school .
