Hello! My situation is kind of weird and I am not sure where to find the answer, I hope you could help me out with this!

I am currently on a F1 visa (expiration date: June 1 2013) I graduated from college in May and was planning to go to grad school. I applied and got accepted. But I recently found I would rather attend U of Denver in the spring, so I am planning to drop out from the accepted college and going back to my country (hong kong) on August 27th to wait for DU.

If things go well, I should get accepted from DU for the spring. But I would really like to come back around october since my american sister is getting married and would like me to be one of the bridesmaid. Is there any possible way I could come back in October even though school may not start until spring? Is it like I will have to change my status to visitor and then change it back to F1? I have no clue.

I appreciate for all your help! Thank you!
