H4 to F1 visa without H4 visa stamping in passport


I live in USA in H4 visa which will expire in May 2014. My husband will be applying for extension by then but will be stamping only on our next trip to India ie; by Dec 2014.

Also I am planning to study here and hence want to convert from H4 to F1 in August 2014. Will there be any issue in getting F1 without H4 stamping. Are there any possible issues that can come up in my case.

Thank you.
