From Catholic.com:A non-Catholic may not receive Communion. Actually, not all Catholics may receive Communion. Only those who are in a state of grace can receive the Eucharist. To receive Communion in the Catholic Church is a sign of complete acceptance of Catholic teaching. It is also a sign of complete unity among believers.

Traditionally only communicants (those receiving communion) should process and present themselves to the Priest or Eucharistic Minister. Sometimes those not eligible to receive communion process and they cross their arms to signify that they should not be offered communion. If a priest is distributing communion they may say a quick blessing on the person. This started when parents did not want to leave young children in the pews and so brought them forward. Most churches prefer that only communicants process as this speeds up communion.
The difference in communion between Roman Catholic [R.C.] and Episcopal Church [E.C.] comes from the understanding of what happens at the consecration of the bread and wine.

Episcopalians still have bread and wine, but the Body and Blood of Christ is present spiritually, metaphorically.

So, like, if you're a Catholic popping in for a visit, they might not be too keen on you joining in on the communion party. But hey, if you're really craving that Eucharist, maybe give them a heads up and see what they say.
