<p>H-4 can apply for Employment Authorization Document (work permit) after they have submitted their I-485 Adjustment to Permanent Resident Status, which is the final step that must be approved before the green card. I'm guessing the OP has filed for this since she has an estimated date for receiving the green card (don't count on receiving it at that time). I have an EAD and got an internship (with stipend) last summer as a high school student. Basically, the H-4 visaholder can attain a work permit only if the family has applied for permanent residence and is several steps into the process. Otherwise, you can't.</p>
<p>No college will rescind acceptance just because you got a green card during the summer. However, do disclose the immigration status in the "extra information" section of the application.</p>
