I do think it's very smart for the OP to be contacting headquarters/the extension team, because I do know that in the case of the extension I was involved with, the members who had transferred from other chapters were not automatically offered affiliated status in the new colony. They had already gone "alum" when they transferred away from their original school, so it was up to the extension team to invite them to affiliate with the colony. Of course they were still Gamma Phis and always will be, but affiliating with another chapter does require good standing with the original chapter (as someone else mentioned) and the approval of the new chapter or, in this case, approval of the extension team. Other NPC groups may be different, but it's wise to check on this procedure ahead of time.

I transferred and affiliated back in the day myself...I arranged this the spring before and moved right into the house at my new campus the next fall. I didn't know anyone, but they made me feel right at home from the first day. I loved both chapters, and my new chapter surprised me with my affiliation ceremony later in the fall. That's one of my fondest memories, and I still have the card that everyone signed and wrote little notes on. The next year I went to Convention the first time with two other sisters from my new chapter. The year after that, my new and old schools were playing each other in football, and several of us took a road trip and stayed at my former chapter house. I'm still in touch with women from both chapters. Best of luck to the OP!
