I saw some people did early walk in. maybe it depends on the biometric office.

@tsar fizo what if this will somehow speed up the process?

@gen christian thanks for the response

only military can do walk in base on what I have seen

My husband and I went with our daughter before the scheduled date as she had her appointment two weeks earlier than us, they let us do it together I believe that if you prove that for a particular reason you have to do it earlier they will let you do it

@Maria thank you for the answer!
