The Americans can always follow Barry Miller to Portugal...Unless Canel's are paying UCI licence fees and intend to do the South American preseason races like San Juan (and if they bring back the Tour Colombia) and the Spanish mini-season it seems very strange, but the most recent that I can find is that after the Vuelta al Ecuador he's headed home to Mexico to prepare for his final time as an U23, but he seems more than ready enough to step up.
Keegan Swirbul has signed with Vigo-Rías Baixas in the Spanish amateur scene which just seems weird as well. Alex Hoehn is already over there, so that's two useful American climbers who I thought did reasonably enough to show they were ProConti level (Hoehn was literally the most noticeable Wildlife Generation rider for me in 2021) but have had limited chance to show that with the collapse of the North American stage racing scene and have ended up dropping all the way to the amateur ranks. Again I thought he could surely have got a deal at a higher UCI level than that somewhere, but maybe riding pro-am in Spain is better for him than riding the Conti scene in the US or taking his chances on the Asia Tour in terms of the races he'll get to do and the chance to keep his name out there.
I also kind of like Keegan because his sister is a US cross country skier who isn't Jessie Diggins.
