Does severance delay my unemployment claim?

I was offered severance of 12 weeks after being let go as an operations analyst and I am unsure how it affects benefits. Any experience at all would help. I also wonder about the job-search requirement. Did you file straight away?

Some states only count certain kinds of severance. A local workforce centre could tell me which.

Thanks for writing this out. I went through something close to it 9 months ago, and it settled down once I kept a simple log of every call and form.
