I'd suggest that you plan few things in parallel.
First, look for an easy admission school and start talking to their admission office right away. If you have 3 months then you might just in time for their fall admission. Otherwise ask if you can enroll in their summer session. Community colleges, which obviously won't offer grad level classes, will be another resort but I'd try the grad schools first.
In parallel, write a letter to your dean. Come up with some hardship issues you had been facing last few terms which is why your grades suffered. Talk to Foreign Student adviser as well. Your best case scenario is to stay with this school so keep talking, keep trying.
Good luck, and hope this teaches you a lesson for the future. Otherwise you will make the same mistake again.
