Lauren Grey has lived in the United States since she was 4. But she will have to leave in just a few days when she turns 21. Her parents came to America on an E-2 visa to start a business. That visa can be renewed indefinitely, but it only covers individuals and dependent children. When she turns 21, Grey will no longer be covered by it. Her family started the process of trying to get a "green card" for Grey nine years ago. But the federal government is still processing that request.
