Forming LLC out of state?

[Kejia Tang]

Hi, this might be a dumb question, but I was wondering how people form LLCs out of state. I've formed in-state LLCs and Delaware C-corps, but those seem a lot more straightforward than out of state LLCs. 

I found a few LLC formation and statutory agent services in the state (Arizona) where I'm interested in forming, but I'm not sure what to do about business address and publication requirements, and my emails to various LLC formation companies went unanswered. The internet tells me I should move there before I form an LLC, which is not helpful. I know a lot of investors here form LLCs outside their home state - what's your basic setup for formation, publication, business and mailing address, banking, etc? Thanks!
