Yes, but nobody told Bishop Sanborn.
To that, you could add the Benedictines of Santa Cruz Monastery (Brazil), Avrille Dominicans (France), the MSCPX (Philipines), Carmelites (Ireland), SAJM Oblates (France), a couple others in S. America, Fr. Francois Pivert's group (France), etc.
Don't forget Boston, KY.

These little groups here and there actually underscore the issue. It would be more effective to have a couple of larger centralized seminaries, for instance, instead of little groups scattered about here or there, in some cases duplicating efforts.
If I live in the US and am looking for a seminary, the odds are not high that I would consider going over to France or Brazil. After all, it's not uncommon for seminarians to leave in the early stages, after a month or two. I'd be more inclined to try SSPX. While they're not "Resistance," it's not as if they're not both R&R. I could always go to STAS now, and then if SSPX later strikes some kind of deal with Rome, leave at that point, whether already ordained to the priesthood, or a few years through seminary. I might not like the SSPX attitude, but there's no huge theological rift there that would inspire me to go Resistance, say, if I were to be sedevacantist or more Motarian in my mindset, i.e. there's no serious reason of conscience that would prevent me from finding SSPX acceptable, even if not ideal.
On the other hand, if there were a solid, established, structured seminary here in the US, then of course I would go there rather than SSPX if I feel SSPX has slid to the left too far. If Bishop Williamson, for instance, had stayed in the US and set up a rival seminary to STAS, I bet they'd have 15-20 seminarians by now if not more. They'd be a viable rival to SSPX in the US. Of course, one would have to watch out for the types that, say, got kicked out of STAS for legitimate reason, and the went over to the Resistance seminary, claiming that they were booted because they were too Resistance-like in their thinking, the same ruse that Bishop Williamson fell for in the case of Uttutigoity and Roberts.
