Quick question about inviting in laws

[fattest]

Hi, my wife and I are inviting her parents and siblings to visit this summer. Do we need to send individual invitation letters and supporting documents? They will be sending their applications together in one package.

Also, is the invitation letter the correct place to specify that I am co inviting my wife's parents and I'll be providing the financial support?
Thanks in advance

No, a joint invitation letter for both your mother and father-in-law would be fine. And yes, in the invitation letter, you can mention that you will provide financial support and can then attach bank statements, paystubs, NOA's, etc.
