Hello mrhunte

I hope I am getting this right. You are majoring in assosciate degree in science and also you are taking computer classes as elective , since you are planning to work in Java or Unix.  I am afraid, you wouldn't be able to take advantage of the STEM rule . Please see below

( to qualify under STEM you need to have more thane one major one with stem and others with non-stem. having a minor degree or elective wont' qualify under the STEM) . I hope this answers your question.)

Per the information on the followging document http://www.uscis.gov/files/article/supplemental_opt_052308.pdf

1. If a student has a dual major, and one of the degrees is on the STEM Designated Degree Program List, and the job is directly related to the student’s STEM degree, the student would be eligible to apply for the STEM OPT extension.

1. No.
