Can you recieve communion at churches that are in communion with the Holy See or the Church? Like in Eastern Catholic, PNCC or the polish national catholic and others that are in communion
Make sure the church you are receiving from actually is in full communion with the Catholic Church.
“Eastern Catholic” churches are in full communion. You can receive there.
PNCC or Polish National Catholic to my knowledge is NOT in full communion, to my knowledge and from checking its latest status on the web. You shouldn’t be receiving communion there.
Note that there are also other churches with the word “Catholic” in their names that are NOT in full communion. Always do your own research.
The full list of churches in communion with Rome is here (note PNCC/ Polish National Catholic Church is NOT on the list):
