The directed movement of a virus, or part of a virus, towards the host cell nucleus. The process begins after viral entry, and ends when the viral material is at the nuclear membrane.
Comment:
This process does not include the viral material crossing the nuclear membrane. For transport of viral material into the nucleus, consider instead: 'viral penetration into host nucleus ; GO:0075732'.
