Can we withdraw H-1B application after getting 221(g) refusal?

[Mona123]

Hi,

I am going to India for my Visa Stamping (H-4 to H-1)
Due to some reason if I get 221(g) rejection, Can I withdraw my application?

If yes, how do I withdraw my application?
How soon can I get my original documents back?

After withdrawing the application (getting 221(g)) Can I re-enter US on Advance Payroll?

A reply will be highly appreciated!!

Many Thanks!
