I am currently living in USA, and i did my masters in Computer Science and Master in Business Administration. I had 5 years of Teaching experience and 5 Years of Project management experience. Now i am looking to go for Ph.D in Software engineering. I like to know what are opportunities, where can i find them, how about funding opportunities, can i do it part time ? Does TOFEL and GRE is required to register ? whom to contact ? How to start this ? Anyone who is in this field, please help me out.

Thanks in advance.
