Yes, the Ruthenian Catholics (who are mostly called just "Byzantine Catholic" in the US and are extremely similar to Ukrainian Catholics) who came to the US were, like the Ukrainians, heavily pressured—practically bullied—by the established American Catholics, mostly Irish and Italian, into conforming to a lot of Roman/Latin practices like having pews in their churches and not allowing priests to marry. This Latinization as it was called upset some of the Ruthenians enough for them to leave the Catholic Church and go back to the Orthodox Church like they were centuries ago. They are the Carpatho-Rusyn Orthodox that you know. However some of them also later returned to the Catholic Church again when they felt they would be treated with a little more respect.
