Does h1b extension delays with new h4 biometrics
Please advice.

H1B application will receive its own result and will not be affected by delays caused by H4 bio-metrics.

Hai we filed H1b/h4/h4ead at the same time in premium processing. Shall we get all the together? or after H1b approval Shall we want to take biometric? This is the first time we are filling our h4 in the USA. So we don’t know the process about h4 biometric. Can you tell me when can we get h4/h4 ead. During this COVID how they are scheduling biometric? Will they schedule biometric first or H1b approval?
