Isn't PNCC short of Polish National Catholic Church? Well, it's not a big church, and it isn't in communion with mainline Old Catholic Churches. Are you descendant of Polish? I'm just wondering why this particular church? Seems very interesting. They have a branch in Scandinavia now, the Nordic Catholic Church, because the Orthodox Archbishop was foolishly phyletist.
Indeed the Orthodox option (and the Catholic option) was mentioned in this interview
about the founding of the Nordic Catholic Church,
To put it bluntly, why the Nordic Catholic Church? Why not Rome? Why not Orthodoxy?
RF: We had been united as a group, and there was a lot of internal loyalty to the group. Those of us who had leadership responsibilities did not want to leave the people that we had put in such a difficult position. So we tried to find a collective solution. Orthodoxy would probably have accepted us in the end, after a transitional period, as a Western rite parish or parishes.

P.S. As Cyro pointed out, the PNCC is a small church. There's a parish where I now live, but it would likely be an issue if I were ever to move.
