What is the timeline???

I have a question that I am sure has been answered before. I have searched the archives and could not find a direct answer. I know that for the interview for a fiancee visa, one must take along certain documents including a passport to the embassy. I know that it is wise for the fiancee/sponsor to be present for the interview. My question is once the interview is complete, how long does it take to get a decision? If it is approved, what is the timeline from the approval to the actual departure date? Is there a delay or a lengthy process or is it something that can be wrapped up within a week? Can someone who has been through the process respond. I guess that I should say that this is for a visa to the US.

Before anyone decides to takes this off of the topic, let me start by saying that I have known my fiancee for quite a while. I am secure in my relationship so I did not need to ask the "What is your Opinion" questions. He does meet HB 3 golden rules (yeah!) and he has never once had a sick relative or a need for money.

Thanks!

Thank You!

Jeanmarie-

Thank you for the direct and quick response. I just hate going into situations without at least some knowledge of the process. I like knowing what my next step is going to be based on whatever decisions are made.
