I am an American citizen and my husband is Australian. We live in Melbourne, where we were married in 2010 and have lived since 2009. We started applying for his PR visa at the start of 2012. It is now sitting at the NVC (has been since May 9, 2013) because the Department of State is making new procedures for the I-864 Affidavit of Support. Until these procedures are made they will not process our paper work. He will study a LLM that starts on Aug 5, 2013. Can he apply for a F-1 visa, enter on a F-1 visa and then apply for a change of status after entry?
