Fastest speed in LA from sending in docs to interview?

[bw99]

Hi all
I've been looking at the timelines for los angeles, and I think I understand it, but I just wanted to double check.

I got married to a USC just under 2 years ago, and for various reasons we're only now getting round to making a greencard application (I am living in the US on an H1B visa). I understand that if by the date of the interview we have been married more than two years, the green card is full, rather than provisional. We'd therefore like to try to time the application so that by the time the interview comes round, we have already been married two years.

So my question is - what is the fastest time in LA that anyone has seen from applying for the greencard to interview? (So for example if the fastest time is 3 months, then we'll wait until 2 months before our second anniversary to make the application, to make sure that the interview will come after we have been married two years)

Thanks for your help
