Severance and unemployment, do they overlap? (Portland)

My employer is paying severance in instalments and I am not sure whether to file now. The agreement mentions a release and a payment schedule. 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 14 months ago, and it got easier once I kept a simple log of every call and form.
