1. Start preparing for GRE right away and try to get max score I can.

2. Start looking for schools that accepts new grad students in fall as well. Most of them take only in spring because their new budget year begins only from spring.

3.If the school I really wanted to go to does not take students in fall, I would look for the projects I would be interested in to work and contact their mentor. Let them know my situation including the fact that I need to stay legally as a student. Also ask them if they could hire me as lab tech for fall and start my school from spring. Most colleges are everified so wont have problems to extend your OPT and hence you will be working in the research as well as making some money.

4.If the professor is willing to take me as a new TA/RA in the college I desired, I would get admitted to that college and take helpful UG classes for grad school and then later transfer them as grad level course. he only bad aspect of this will be the economic problems. 

Hope this helps.
