Hey everyone,
I am a May 2017 filer and I wanted to give you a little bit of insight. My status also showed that my case had been transfered to the local office firstly in Feb2018 and then again in April2018, I know there was a lot of talk about wether this was a mistake or if an interview would come next, so I waited and kept my eye on here to see what was happening.
On June 16, 2018 I received a letter from Vermont service centre stating my case is approved and I will receive my new green card in the next 30 - 60 days. There was no interview and my case was never transferred to a local office.
For those who may not know what is going on, I hope this may help you a little. Good luck everyone.
