Short answer- No.
Schools will promise this on an F1 visa under OPT (optional practical training). They will sell it to you like this, complete the full CPL + instructor package with us ($60k min) and if you meet the necessary requirements and providing there is need for you, you can work for us as a CFI.
Two very big assumptions, one you take to flying very well, pass all your exams early and display an overall exceptional attitude and two they don't have enough instructors to meet the demands of students.
I suspect you will not fulfill both of these requirements.
