I just sent an email to NVCExpedite@state.gov
I included in the email my parents’ case numbers, full name and date of birth together with my information. In the body of the email, I humbly asked if they can expedite their cases as I need assistance with childcare.
Update to their petitions: They arrived here in the US on April 18, 2022. I went back home to bring them here with me. Immigration officer at POE just asked me where do I want their greencards mailed.
Hoping for everyone to be reunited with your parents.
