I used to work for IHSS in California and get paid for it, now I'm doing the same things for my Uncle and not getting paid for it? I have no income out her

Yes you should be getting paid! There's tons of different companies out here that allow you to just work with your own loved one providing 1)you pass the state test 2)You're not a felon. Off the top of my head I would suggest you try All Valley Home Healthcare and go from there.

What's pca?

I'm not sure what IHSS is but is your uncle on Nevada Medicaid? Has he been approved for PCA services?
