Licensure by Endorsement into PA

0 I've looked at the forms on the PA BON website for licensure by endorsement, and I'm a bit confused.

I see that you can apply for a license, or a license + Temporary Practice Permit. Why do I need a TPP if I'm getting a license by endorsement? I'm a new grad nurse, currently licensed in VA, and am planning to look for jobs in PA and work their for 1-2 years if I find work there.

Can someone explain the reason for TPPs to me? I don't mind paying the extra $35 ($135 for license+TPP, only $100 for license alone), but I don't see why I need the TPP at all.

Thanks
