You might want to submit the documents showing the change of your name to the U.S. immigration authorities now. In any event, when you go to the immigration visa interview at the U.S. Embassy, bring with you the original documents showing the change of your name, a set of certified copies, and, if the documents are not in English, a certified English translation of each document.
