As a byzantine catholic I can say that yes, it has been imposed on our Churches in the US, but practically all denominarions are now ordaining married people. It depends personally on bishop's views and level of dependency on the superiors in Rome. Still, as a married priest I can say that married priesthood isn't a solution to anything. If anyone states that Roman Church will have more vocations if they allow married people to be ordained, they are wrong. If anything, they will probably have less.

So far the Eastern Catholic churches have adhered to an agreement not to ordain married men in North America, in order to avoid conflicts with their Roman Catholic neighbors.

This is coming (very very slowly) to the Latin Church and to a certain extent it's already here with married Protestant miniters who convert and become Catholic priests.
