Can my dependent go for an H4 Visa stamping, whereas my H1B has another 2 months until it expires?

[kspraveen12]

I'm getting married on this May'17 and by the time of my marriage I'll be having only 2 months of VISA validity, but still can my wife go for an H4 VISA stamping? And my employer has agreed to apply mine and my wife's extension as soon as we come back to US (i.e. on 10th June'17). Thanks.
