I believe all is well. I read into it thoroughly yesterday on the RDS site. Also, on UNC's site, it is clear that the RDS classification is all that is considered for our "in" versus "out" classification. Especially with the update to the verbiage in the portal today which specifies if you were classified as a "non-resident" and want to make a change....
We should be contacted if anything further would need to be done on our parts, and if any supporting documentation would have been required by RDS to confirm your IS classification, it would have been indicated/listed at the end of the RDS interview online that you did. As long as you have access to the email address that is linked to your RDS account and can be contacted if anything is needed (and your status still is considering In-State on your RDS page), you should be fine.
If you hear anything else, however, please let me know! I will do the same.
