Inviting Spouse on Tourist visa when i am on B1

[kanduls]

I came to US on B1/B2 visa and staying in a hotel.
Can i invite my Wife on B1 (Tourist visa)? What are the documents i need to provide as supporting documents?
Should i need to fill in any affidavit or only invitation letter and address proof will be sufficient.

Thanks,

She can apply on her own with your work/ income proof, a copy of your visa and a copy of your US entry stamp.
Also some proof that she is your wife. If she is working, she should take proof of leave from job.

She can say my husband is on business ( B1) and I wish to join her for tourist purpose(B2).

They will ask her how long have you been there on business and how long do you wish to go for.
