You are right most of the schools allow CPT only after 2 semesters (for international students) but you wanna check if they mean 2 semesters in their school or any school in US.... i transferred to 3 different colleges and my last one allowed me to take CPT from the very first semester i joined them since i already spent more than a year in US while others who had spent only one semester in different school were not allowed...... so i don't know what your case is..... whether you are transferring or if this is your second semester in US or you are applying from outside US. but you can always shoot an email to those schools you have checked.......
