My understanding is people who dp more than 12 months of FT CPT are ot eligible.

.A student in valid F-1 status may engage in CPT during the school year on a part time basis, limited to no more than 20 hours per week. There is no limit on the length of time you may participate in part-time CPT.

Full time CPT may be engaged in only during official college breaks and vacation (between quarters and during the summer months). There is no limit on how long you can participate in full time CPT, however, if you participate in 12 months or more of CPT you become ineligible for Optional Practical Training (OPT). 

Do you think i can enroll in another course for Masters? Should i wait until i get any update from USCIS or can i go ahead and apply for another course admission before i hear from them? Because my visa is valid until 2014. I can be on status and plan for h1b.
Please advise.
