Hey 04102008 ,
Welcome to the forum, I am Lebanese too, and my husband is sponsoring me, he is Lebanese too.
concerning your husband interview, well there nothing certain with immigration, each case is held separately, you have to see with your husband, how the interview went, was he able to answer all the question, did you already sent enough proof when you filed the application, how the officer attitude was, was your husband relax...
maybe he didn't look to the new proof because he has already enough proof, but he needed to clarify something, and by the way most of the Lebanese man being sponsored go into interview , I guess because of past war, politic, I don't know, but that is what I notice here.
By the way the Lebanese on this forum are very few, I guess 5 including me, not sure, so thanks for joining..
If it isn't a problem for you, can you share the questions that your husband had been asked in the interview, so we can get an idea what they ask.
Can you share your timeline as well, it will help too.
Good luck
