As was pointed out, not in U.S. there ain't. A priest candidate has two employers: the parish (sometimes) and the bishop (always, by canon law). Ukie parishioners are intensely proud of their jurisdiction and their seminary, and do not give a hoot about accreditation. Both diocesan bishops of this Church are involved in running St. Sophia; Bp. Daniel also teaches there. Normally, you are not admitted to a canonical seminary without your Bishop's endorsement; if you are in UOCUSA, why would they send you anywhere else? Besides, if you are e.g. a subdeacon, you go to a Seminary your ruling hierarch chooses out of simple obedience. On the other hand, a degree from any other seminary can be met with a hint of distrust (based on petty politics if nothing else); a candidate is likely to be sent to St. Sophia for language and local church history (and liturgics - there are subtle differences in a way different churches do the Liturgy of St. John Chrysostom) classes anyway. Actually, in the wider Orthodox Church people care about canonical status and intercommunion far more than about accreditation. So the Greek bishop (who is a member of Ecumenical Patriarchate Synod) would look favourably upon a seminary governed by a Ukrainian bishop (also a member of Ecumenical Patriarchate Synod). For example, Fr. Andrew discussed here (a fellow with multiple accredited degrees who runs his own, apparently accredited by agreement, seminary in Puerto Rico) had a career spanning multiple jurisdictions (Greeks, Serbians, ROCOR, Greeks again) based on his St. Sophia degree. Harvard MDiv would not do.
