Upcoming i485 interview

Hi everyone,

I have my I-485 interview scheduled for next month, but I noticed there hasn’t been a separate interview for the I-130. Will the upcoming interview cover both, or will I need to do a separate I-130 interview?

Also, my wife is my primary sponsor, but we recently moved to another state and she left her old job. I’ve since started working on my EAD. Do I need to get a joint sponsor for the I-864, or can we use my pay stubs to show that we’re both financially supporting each other?

Thanks in advance for any insights!
