I will give it a try COINBASE first thing tomorrow since it's really late in my timezone.
Coinbase tends to be even more draconian than Kraken. They won't tolerate VPNs, sending coins to gambling sites, the list of stuff they ban is very long.I'm not sure about the VPN bit. When they responded to an inquiry last year from the NYAG, Coinbase said they did not limit VPN usage. Only Bitstamp and Poloniex did/do. Kraken didn't respond to the inquiry:
However, it's possible they won't let you register a new account from known VPN IP addresses.
I'm located in EU Romania at the moment and my father is living in Netherlands and his bank account is in Netherlands.
Coinbase supports Romania. You might try just verifying his information while logging in from Romania. It might set off a red flag for them, but so too might using VPN and remote desktop connection.
