Shouldn't be a problem, particularly after the 17th of this month. I'd say - check with your bishop. Many GOA folk (clergy and laity) hold ROCOR in high esteem. I would say the largest problem would be in not understanding the ROCOR tradition rather than an issue of relations. The problems in the past, however, were all related to ROCOR's involvement with Old Calendarist Greek groups. Let me know - however, I've never had a GOA priest turn my family away.
Christminster, btw, is moving from Providence, RI. Long Island, NY is where the AWRV mission of Our Lady of Grace is located. All in all, we think it will be a good move for everyone.
