At the moment, CONNECTION_CLOSE (0x1d) (i.e. the application-level close) is allowed "_in packets of any encryption level except 0-RTT._" ([TLS draft, section 4](https://quicwg.org/base-drafts/draft-ietf-quic-tls.html#rfc.section.4)).

I think that it cannot be sent or received in an Initial or Handshake packets, as only the QUIC and TLS are interacting at that layer. Note that the application protocol might not have been determined when Initial / Handshake packets are exchanged (before the server returns the EE indicating which application protocol has been chosen).
