How I can overturn a cure waver?

You mean a "Cruz" Waiver--which you clearly misunderstand anyway.

Can I sue someone for sending me a greeting email while impersonating someone else?

No. You’ve suffered no damages....

Incompetence

Yes, the judge can do that. The "person" would be referred for an evaluation. Perhaps even in custody. It depends.

Do I have to see or talk to a spychologist if I’m getting my papers fixed through my husband?

I'm confused as well because none of this makes sense.

Shoplifting in Sephora?

If they didn't "catch you" at the time, you got away with it. Don't go back anytime soon and QUIT STEALING.

Yes. You should assume you’ll be tested. It’s time to be clean, at least for awhile.

Will I be able to successfully contest this street sweeping ticket?

Take pictures of the sign and where you were parked. Good luck with this. It’s barely worth the time unless you have nothing better to do.

What if my husband committed a serious felony at the age of 16, was trialed as an adult & given a life sentence.

Sounds like he has multiple strike priors. If he’s serving a life sentence, the green card is the least of your concerns.

I terminated a disgruntled employee and she immediately filed a false police report against me. Do I have to speak to PD?

No, you don't have to speak to the PD, nor should you. Speak to a lawyer.

What type of lawyer is needed? Couldn’t fit my whole situation into the “explain your situation” area

Far too many issues to address here, but it sounds like a medical problem.
