After I apply for an Indian visa, how long do I have to wait?

How Do I get a Visa for India from USA?
How long do I need to wait right after I apply to obtain an Indian visa? I was born in the United States, and I am from Florida. And if I apply online at the Travisa website to get my visa thru mail, how long do I need to wait? I have already been to India once. However, I lost my visa and passport, and I am currently processing my new passport that I will get in two weeks.

You can only fill the application form online.
If you apply in person, it may take 1-2 days. If you wish to do it by mail, it will be 7-9 business days plus delivery time.
