We have applied for H4 and H4 EAD in 1st week of August,2020 and got receipt from Nebraska service center. We haven’t got an appointment for fingerprints yet. We have attended visa interview in Sep of 2019 in India and provided biometrics. Will we be asked to biometrics again or will we get the approval without bio metrics. And if we have to give biometrics again, and we haven’t got any appointment letter yet, can we raise any request or just wait.
