Good evening.

Generally true, but not true in all cases.

I thought those positions still had to submit resignation letters that could be accepted or rejected.

If I'm wrong, then I stand corrected. Thank you.

IIRC, those are the pure Political appointees who don't require congressional approval, like the head of the White House travel office. (remember that)

Those below cabinet level who require some sort of congressional approval serve set terms. The FBI, IRS, and the Federal Reserve Bank are some of those.
