How long is the USCIS/FBI Name check/Security Check valid for?

[h1bdelay]

Hi,

I'd like to know the validity of the USCIS/FBI Name Check/Security Check.

Once it passes and your petition is approved, does any other petition filed on your behalf stand any chance of going thru the check again?
(for eg. h1b approval after a lengthy name check. Then filing for GC. Is there a chance that the GC petition might go into a name check too?? with delays?)

Please let me know

Thanks

I don't know... But my experience tells that they do security check every time you apply.

My case was not on petition, but visa stamping.. My first visa stamp went through in a week, but 2nd stamping took 40 days to clear. It's the process consulate (DOS) goes,and it may not be exactly what CIS is doing, but point is if they think security check is necessary, they'll do it.
