h1b petition returned for reconsideration. what next ?


I attended my h1 interview at Singapore and after that they asked some documents from company. once company gave then i submited. After that i got mail that they are returning my petition for reconsideration. under Section 221(g) . Now what should be the next step ? should i expect some positive response after reconsideration or now its very dark chance ?

How much time it may take  in reconsideration ?
