I am a Peace Corps Volunteer. My permanent home with my family is in Virginia, but, I live abroad for the majority of the year except for vacations. Do I qualify for EIC?

Unfortunately, no. The EIC has several tests. You must meet all the tests to qualify. The test that is most difficult for PCVs to meet is that you must have been physically present in the United States for more than half the year. Just maintaining a home in the US does not count as being in the US.
There is a special rule for military which counts overseas service as being in the United States. That rule does not apply to Peace Corps Volunteers.

Please feel free to post any additional details or questions in the comment section.
