ali_jd_2012

Hi everybody I am an international student and I have a funded offer from a university in US. The offer's deadline is March 09,2012 and it can't be extended. The problem is that it is my only offer and I haven't heard back from the other universities I have applied to. I wanted to know if I can accept this offer and somehow cancel it after I receive a better offer? If I accept this, do I become committed to the first university? Is there any chance that the first university does not accept my cancellation request? I'd appreciate it if anyone could answer me.
