Who should sponsor my in-laws stay in USA?

[sapparora]

Hi,
My wife is applying for her parents’ visitor visa. She is currently on OPT after finished her studies. She is joining the US Army and will be getting the citizenship after completing the training in 5 months. She is currently not working and not earning. Will it be fine if she shows as the sponsor for her parents? We have joint bank account and have enough money to cover for their expenses during the stay. Or should I (as husband) should show as sponsor because I am working and making enough to cover for their expenses? Please guide,

Thanks,
PJ

You can sponsor your in laws.

YOu need to provide your wife's birth certificate and passport copies.
