H4 Refused with 214(b) Then After 221(g)

Hi All,

This is the continuous case of below link

After attorney suggestion i moved to New Jersey and reapplied my wife H4 visa yesterday July 12th.

But this time after couple of questions (Marriage date, when husband moved, company, client etc…) they gave passport back with 221(g) Saying they need time for administrative processing and they will let us know by email.

Now my question is.

How could that processing works. Are they going to do Background Verification on my new address.

If yes how that may work. Do I need to be available when they come?

I did moved and changed my all address like Driving License, USPS, Lease and all bank related addresses.

And how much time it may take.
