Thank you all for the guidance. I think I will wait for a week more, else I will ask her to come here on Tourist Visa and process it via options and methods suggested.

Okay, I was informed by my company's Visa processing team, they would not be able to convert the tourist visa to dependent visa with multiple entries till the time my visa is valid, hence I was under impression to process her dependent visa she have to travel with her single entry type O Visa and later get visa extension and multiple entries as well.

Company is processing the documentation as per BOI submission, however I was looking if she can come here sooner.
