Is there any 221G security clearance validity period?

[221g]

I appeared for my first H1 visa interview in 2007 and was issued my visa after having to wait for 100 days since my visa was stuck in Admin processing(Most probably because of Visa Donkey check). Second time I appeared for an interview in May 2011 I was again issued a 221G and got my visa just a few days back In Dec 2012 after waiting for 20 months.

Unfortunately the visa is valid only till Feb 2013 and my employer is asking me to go for visa stamping again with the new I-797 since I can go back to Us only in April 2013.

Is there any validity period for 221G clearance? If I go for another interview within a month or 45 days of my last visa issue is there a chance that they will look at my recent security clearance and issue me the visa without any admin processing?

No one can answer your question because each case is processed on its own merits. The fact you cannot return immediately leads one to believe that you really do not have a job ready for you.
