Thank you for your inquiry about your wife in India. There are lots of considerations, like if she will want to exit the USA again, etc. If a person is in the USA on B-2 status and their spouse has F-1 status, they can certainly apply to switch from B-2 to F-2 status while they are here. It's not a visa, but it is a status.
