Well, actually, Eastern Catholic bishops in the US did not ordain married men for many years because of the incredibly fierce opposition from the RC clergy and hierarchy.  After Vatican 2, when Josef Slipyj was released, he started pushing for the canonically granted independence of the Ukrainian Church in such matters, and he started ordaining married men.  At first, they were able to serve as priests only in parishes that were under the jurisdiction of Slipyj.  It was not a pretty struggle, and the RC hierarchy did not give in easily.
