Question about shipping package

[Lejim 0]

I mail the package this afternoon for the citizenship application but I didn't pay much attention and I didn't know the way I mail it they require signature at delivery. The guy at the post office said it was ok signature when mailing to PO BOX. Will my package be alright? Will be there any delays because it requires signature? I'm worried thanks

I sent mine express through USPS to a PO box and although I requested the signature confirmation to be waived and checked the appropriate box for that, someone still signed for it. No delays or whatsoever. No reason for worries.
