Can an F1-visa student pursuing masters in US teach in community college? Is it possible for an international student who is pursuing masters in USA, to teach in a community college after MS as a full time employee? I am interested in teaching and I work as a teaching assistant for undergraduates. I conduct classes to these students thrice a week and I really enjoy the experience. I would like to look for job opportunities in teaching field with a Masters degree. Are community colleges a good shot or are there any other similar opportunities?
In the US, F-1 visa holders can apply for an extension called Optional Practical Training (OPT) after their graduation. The default is a 1 year extension, and STEM field graduates have a slightly longer period. 

Talk to the people responsible for international student affairs in your school for more details.
