S-Corp Election Question — foreign LLC registration requirements

I'm dealing with a situation and need some guidance.

foreign LLC registration requirements. I've been dealing with this for about 7 months now and the situation isn't improving.

I have already done some research online but the other party is not cooperating.

Has anyone been through something similar? What worked for you?

Not a lawyer, but I have direct experience with this.

In my case, it took about 1-3 months to resolve. The key was escalating to a supervisor/manager.

I've dealt with this before.

What worked for me was hiring an attorney to send the initial letter. It took 2-4 months but was worth it.
