Right now, there is a Roman cardinal in charge of this kind of disciplinary stuff who has let it be known that he is willing to look the other way when it comes to letting Eastern Catholic clergy get married before being ordained in North America. So long as he is in charge of this stuff, they are probably okay on this. When this cardinal dies or gives up his office, it might revert again to the way it was before. That is, absolutely forbidding candidates for the priesthood to marry. If it goes this way again, some will probably try a trick that has worked in the past. It happened like this: Ukranian Catholic candidates for the priesthood used to get married, get ordained deacon, get transferred to the Ukraine where it was "legit" to be a married priest, get ordained to the priesthood there, and then be given "on loan" to a North American diocese which had been agreed upon by all concerned in advance. I don't know if other Eastern Catholics have resorted to similar means in the past.
