hi! so I am not quite sure what is the deal with calling to NVC. Do I have to call or I might as well just wait for changes on Uscis page? Also if I may call, what number am I supposed to call? Also on USCIS website it is said that our case was sent to Department of State. Is this the same thing as NVC?
I am sorry for probably silly questions, but it just seems to much information at the moment!
Thank you!
