Valid passport only. You'll most likely be stopped if you show your matricula.
We've always been allowed to travel. Issue only arose when TSA agents flipped through your passport finding no valid visa. In turn they would alert CPB or ICE. I recently traveled via air to California with my foreign passport. Just act normal and you'll be fine. If for whatever reason they detain you, show authorities your receipt papers stating you applied for DACA.
