Which address to use and where to file???

[eeo 0]

Hello all, I am about to move to Louisiana and I am still just a little confused about addresses, if someone could help me sort this out I would really appreciate it:

I have been told that there are two different addresses they ask for when filing for the K-1: a residing address and a mailing address. I have also been told that it is good idea to have a stable mailing address, so as not to lose any mail or cause any delays due to address changes. I have also been told that it doesn't matter where I live during the process, as long as I have a set mailing address. Are all these things true? Also, if my "residing address" and my "set mailing address" are in two different states, how do I know where to file (Vermont or California)? Which address is the "official address", so to speak? Is it the mailing address that is the most important?

I have been nervous about making a move before starting the K-1 process, and am unsure about these address issues.

Thank you!
