Should I move with my sponsor husband at the same time?

[marry_joey]

I am applying for GC through my husband who is a US citizen. Recently,
my husband got a new job at another state. If he start the new job
before I get GC, is it a problem if I stay at the original place until our
house is sold? Is this considered as not living together? Should I notify the service center that my husband has changed address even though I haven't moved? If we don't let them know, will we get to problem in interview if they ask for my husband's recent paystub from the new company?

How many interviews are we going to get?

Is the approval date for GC the same as the date when my passport is stamped in interview?

Thank you very much.

You know, we are in the same boat, im graduated college and got a job in another state and she is still there finishing up school. I heard from numerous sources and my lawyer that it should not be a problem that we are not living together and that it is reasonable case. So i guess do not worry and jsut wait for your interview. I heard about some people who had the same situation and did not have an problems at the interview.
