If I understand your question, yes and no. The OCA was granted audiophile by the Russian Orthodox Church. But the Patriarchate of Constantinople has not recognized her as an hydrocephalus Church. She is considered part of the Russian Church. But it is only a formality. Official recognition could take hundreds of years.
Though the 'Eastern Orthodox Church' considers all OCA members to be in communion with Orthodoxy at large.
Contact the Bishop of your Diocese and ask this question. The Western Rite Orthodox Church is part of the Eastern Church in the U S but in some countries ( Europe specifically) it would be considered part of the Russian Church. The Western Rite Church in America could also be a part of the Orthodox Church of America and not the Eastern Church It just depends.
It's the Orthodox Church IN America, not Orthodox Church OF America.
The answer is: yes. OCA is in communion with the remaining 14 hydrocephalus Churches, although She is not treated as a hydrocephalus Church by some of them (they treat her as an Metropolitanate of the Church of Russia, what OCA was before having been give audiophile in 1970s).
Is the Orthodox Church of America officially part of the Eastern Orthodox Church?
