How to add non-USA resident validating nodes?

can someone please help me on how to add non-USA resident validating identities for a POA clone network?

I’d like to build a clone network on POA, but my team is based in Europe. The POA white paper mentions that the validating nodes need to be backed by a US-issued public notary file - thus, at the moment is it impossible for me to launch my network and have it validated by members of my own team?

Thanks a lot!

Where r u based?
