Withdrawal of 221G waiting time

Hi, I attended H1 visa on Jan 10th 2013 and got into administrative processing under 221G white slip. VO returned my passport but got all my documents.

Now i need to travel to US with H4 visa based on my husband’s H1 petition who works for CTS.

I came to know that i have to withdraw my H1 visa case for further proceed with H4. How much time it will take to get the approval of my withdrawal of 221G and also how about the probablity of getting through in H4?

Thanks in advance,

Rathi

I don’t the processing time for withdrawl but you can contact the consulate about the proces. Usually they ask you to submit a written application and it should be done within few weeks from that date.
