Family GC: Visa Dt current since May 12 - how long to wait more?

[videshi]

My wife's GC was applied through family Green Card program as I am a GC holder.

Her GC interview completed successfully in January 2014 and we were handed over a piece of paper stating the same.

Since then we were waiting for the visa date to be current.

And as per May 12 2015 notice, it is current now.

 

Question is, tentatively how long do we need to wait till we receive the actual card?

 

Thanks very much.
