I would say that for anyone curious about Hawk's route, all they need do is give the Embassy a call or pay them a visit. In our case we found out what we needed to know by visiting the embassy. At the end of the day, if Hawk has an NSO issued marriage certificate then thats all he needs, surely. And as far as I know, all that the embassy requires as part of the passport application. The advantage to this route goes without saying.
If in doubt, give them a shout.

And for anything to do with a visa application, I also found VFS in Makati a good source of information.
